As a carbon-free energy source and carrier, NH3 is an essential component used in agriculture, industry, and medicine. Currently, the main process for industrial ammonia production is the Haber-Bosch process, which is highly energy intensive with the emission of large amount of CO2. In contrast, electrochemical ammonia synthesis is a promising alternative for the Haber-Bosch process owing to its environmentally friendly nature, low energy consumption, and zero CO2 emission. Meanwhile, as a widespread source of nitrogen in industrial wastewater and contaminated groundwater, nitrate has received extensive attention as the source for the synthesis of NH3. In this study, a Ru-Cu/Cu2O@Ti3C2 catalyst was successfully prepared by combining highly conductive Ti3C2 MXene with Ru-Cu/Cu2O@C. In 0.1 M KOH and KNO3 electrolyte, the Ru-Cu/Cu2O@Ti3C2 exhibited excellent nitrate reduction reaction (NO3RR) performance, achieving the highest faradaic efficiency of 48.3% at −0.7 V with a corresponding NH3 yield of 128.35 μmol cm−2 h−1. The excellent catalytic performance of Ru-Cu/Cu2O@Ti3C2 was attributed to the synergistic interactions between multivalent Cu/Cu+, abundant metal active centers of Ru, and the excellent electrical conductivity of the two-dimensional Ti3C2 MXene. This study may provide a practical pathway for converting nitrate wastewater to valuable ammonia products.

The conventional Haber-Bosch method for the ammonia synthesis process requires high temperature and pressure. Electrochemical synthesis of ammonia, an emerging ammonia synthesis technology, is a promising approach for sustainable ammonia production that is energy-efficient and free of greenhouse gas emissions. The design and development of high-performance catalysts are the keys to promoting the sustainable ammonia production process. This work synthesized a PdCu alloy catalyst loaded on a graphene oxide carrier through a simple liquid phase reduction method. Which greatly enhanced the catalytic performance with an ammonia yield of 1.62 mg h−1cm−2 and Faradaic efficiency of 38.2 % under the nitrate reduction ammonia synthesis (NO3RR) reaction at an overpotential of −0.4 V. For the nitrogen reduction ammonia (NRR), the ammonia yield was 20.83 μg h−1 cm−2 with a Faradaic efficiency of 3.8 %. This study may provide a new idea for material design and promote ammonia synthesis development under ambient conditions.

The solar-driven interfacial evaporation system has attracted much attention in recent years due to its reduced heat loss and accelerated steam generation. As a low-cost and readily available resource, wood is widely applied as photothermal materials in solar-driven interfacial evaporation system because of its superior water transfer and heat loss prevention properties. Herein, a simple, mild, and cost-effective method is employed to fabricate wood-based photothermal materials. The results demonstrate that the solar absorption rate of wood-nigrosine is more than 97.5% across a wide wavelength range (200–2500 nm), and an evaporation rate of 1.46 kg m−2 h−1 and evaporation efficiency (86.1%) are achieved under 1-sun illumination (100 mW cm−2). The solar-driven interfacial evaporation system based on wood-nigrosine exhibits strong structural stability and processing capability for dyes and seawater.

High entropy materials (HEMs) show great potential as electrocatalysts for oxygen evolution reaction (OER) thanks to their interesting four-core effect. This paper presents the first systematic summary of the key factors in the synthetic methods and their influence on the structure and OER properties of HEMs (including complexing agent, synthetic temperature, and calcination atmosphere). Optimizing the components of high entropy alloys and compounds by introducing heteroatoms (such as O, S, P, N, C, and B) can enhance the chemical configurations of active sites and thus enhance the intrinsic OER kinetics. In addition, this paper emphasizes the importance of the electrocatalytic influence mechanism of the four-core effects (including the high entropy effect, lattice distortion effect, cocktail effect and sluggish diffusion effect) on catalyst structure and their OER performance. Finally, we outline the current challenges and future development directions, aiming to offer crucial insights for creating economical and efficient HEM-based electrocatalysts in the OER field.

Through theoretical screening of various amino acids, our study has effectively created a robust technique to improve the performance of aqueous zinc chemistry by introducing histidine or arginine as electrolyte additives. It was discovered that histidine and arginine may create an interphase on the zinc surface, optimize the electrolyte's solvation structure, and modify the structure of the electric double layer (EDL). The mechanism that results in homogenized and faster zinc ion transport is known as “N-coordination, O-anchoring”. Outstanding long-term cycle stability and extraordinary rate performance have been made possible by this optimization technique, especially in the face of extreme circumstances like high depth of discharge (DOD) (68%), high areal density (80 mA h cm−2), and high current density (40 mA cm−2). Surprisingly, at high current density (40 mA cm−2 & 40 mA h cm−2), ultra-high deposition capacity (56 240 mA h cm−2) was reached, surpassing all previously reported values. We think that this all-encompassing optimization strategy, which is simple, environmentally friendly, and effective, has a lot of potential to be applied to other multivalent ion batteries that are dealing with comparable problems. Our research advances scalable and sustainable battery technology by providing a roadmap for the development of innovative energy storage devices.

The pursuit of sustainable and efficient energy storage solutions has increasingly focused on aqueous ion batteries (AIBs), which offer notable advantages in safety, cost-effectiveness, and environmental sustainability, positioning them as viable alternatives to traditional lithium-ion systems. However, the broader adoption of AIBs is contingent upon advancements in the development of stable, high-performance electrode materials and aqueous electrolytes. In this context, MXenes, with their two-dimensional structure, versatile assembly, and superior electrical conductivity, emerge as a pivotal material. They play a crucial role in facilitating ion transport, enhancing electron percolation, stabilizing interfaces, and boosting electrochemical activity. This review provides a comprehensive analysis of recent advancements in MXene-based AIBs, with a particular emphasis on zinc-ion batteries. We delve into the fundamental roles of MXenes in synergy with various active materials, including both inorganic and organic cathodes, as well as metallic anodes. Additionally, we present a summary of the strategies employed in creating composite assemblies for electrode applications. By offering an integrated perspective on the application of MXenes as multifunctional components in AIBs, this review aims to serve as a valuable resource for guiding future research and innovation in the community.

The inferior electrical conductivity and sluggish lithium storage kinetics of conventional high-entropy oxide (HEO) are critical issues hindering their commercialization. The high electronegativity of metalloids can ameliorate this predicament by altering the electronic configuration of HEO compared to metals. Herein, metalloid phosphorus doping in spinel-type HEO (PxA1-x)B2O4 (A/B = Cr, Mn, Fe, Co, Ni) (P-HEO) is achieved through a facile sol–gel process. The metalloid phosphorus doping facilitates the transfer of electrons from transition metal sites to phosphorus-doped sites, resulting in the formation of electron-rich and electron-deficient local regions on the HEO surface and is conducive to an increase in the total number of active lithium sites in the electrochemical reaction process. Density functional theory calculation reveals Li adsorption energy on the synthesized P-HEO is only −1.102 eV, demonstrating that the phosphorus doping enables a strong electronic coupling between lithium ions and P-HEO. Furthermore, metalloid phosphorus doping also leads to oxygen vacancies formation and lattice distortion, which significantly enhances charge transfer efficiency and diffusion kinetics and results in the enhanced lithium storage performance with impressive rate capability and long-term stability. These findings provide valuable insights for the design of lattice-engineered HEO as versatile electrodes for future energy storage applications.

Electrochemical ammonia synthesis presents a sustainable alternative, offering the potential for enhanced energy efficiency and environmental benefits compared to the conventional Haber-Bosch process. In recent years, the electrocatalytic reduction of nitrate to ammonia (NO3−RR) has emerged as a crucial approach for achieving sustainable NH3 production. To enhance energy efficiency and successfully convert NO3− to NH3, it is essential to investigate cost-effective electrocatalysts that provide high Faraday efficiency and demonstrate adequate stability. Ti-based materials are considered ideal candidates as catalysts due to their environmental friendliness and robust stability. This review initially summarizes the nitrate reduction reaction pathway and concisely discusses the impact of the potential intermediates and reaction steps on the overall reaction efficiency and product selectivity. Subsequently, an overview of the fundamental characteristics of Ti and TiO2 is presented. Additionally, the research process on Ti-based electrocatalysts in the electrochemical reduction of nitrate for ammonia synthesis is summarized. Finally, the design strategies, such as heteroatom doping and the introduction of oxygen vacancies, to enhance catalytic efficiency and selectivity are presented. Through this comprehensive review, we endeavor to furnish researchers with the most recent insights into the application of titanium-based electrocatalysts in nitrate reduction reactions and to stimulate innovative thought processes on the electrocatalytic synthesis of ammonia.

The purification of carbon monoxide in H2-rich streams is an urgent problem for the practical application of fuel cells, and requires the development of efficient and economical catalysts for the preferential oxidation of CO (CO-PROX). In the present work, a facile solid phase synthesis method followed by an impregnation method were adopted to prepare a ternary CuCoMnOx spinel oxide, which shows superior catalytic performance with CO conversion of 90% for photothermal CO-PROX at 250 mW cm−2. The dopant of copper species leads to the incorporation of Cu ions into the CoMnOx spinel lattice forming a ternary CuCoMnOx spinel oxide. The appropriate calcination temperature (300 °C) contributes to the generation of abundant oxygen vacancies and strong synergetic Cu-Co-Mn interactions, which are conducive to the mobility of oxygen species to participate in CO oxidation reactions. On the other hand, the highest photocurrent response of CuCoMnOx-300 also promotes the photo-oxidation activity of CO due to the high carrier concentration and efficient carrier separation. In addition, the in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) confirmed that doping copper species could enhance the CO adsorption capacity of the catalyst due to the generation of Cu+ species, which significantly increased the CO oxidation activity of the CuCoMnOx spinel oxide. The present work provides a promising and eco-friendly solution to remove the trace CO in H2-rich gas over CuCoMnOx ternary spinel oxide with solar light as the only energy source.

Synthesis of highly active and durable electrocatalysts is very important to enhance the reaction rate of methanol oxidation reaction (MOR). Herein, we reported the synthesis of vanadium-doped cobalt nanoparticles trapped in carbon nanotube (V-Co@CNT), which was realized through one-step calcination of Zeolitic Imidazolate Framework-67 (ZIF-67) grown on V2O5 nanorods (V2O5@ZIF-67) with the assistance of dicyandiamide (DCDA). The results of experiment verified that because of the appearance of lower valence vanadium during the carbonization of DCDA, the synthesized V-Co@CNT shows better MOR performance than V-Co@CNR (direct carbonization of V2O5@ZIF-67 without using DCDA) in 1 M KOH + 1 M CH3OH. For the MOR||HER test, at 1.45 V, V-Co@CNT shows an excellent stable current density of 7 mA/cm2.

SnO2, the most promising alternative to TiO2 as the electron transport layer (ETL), has attracted great attention for perovskite solar cells (PSCs) due to its high bulk electron mobility, good band energy at the ETL/perovskite interface, and high chemical stability. To enable more efficient carrier transfer and extraction, elemental doping with different metal cations has been studied in SnO2 ETLs. However, the systematic investigation of the doping mechanism lag far behind their efficiency promotion. In this paper, elements of the same main group (Li, Na, K) and period (K, Ca, Ga) have been selected for doping in SnO2. The results showed that among the properties of the dopants, the electronegativity has the greatest influence. The smaller the electronegativity of the doping species, the more conducive it is to carrier transmission and separation. The corresponding mechanism was proposed and discussed. At last, an efficiency of 20.92% of PSCs based on SnO2-K was achieved. In addition, the doped SnO2 is more beneficial for the growth of perovskite crystals, thus reducing grain boundaries and enhancing the stability of the device.

The solar-driven interfacial evaporation system has attracted much attention in recent years because it avoids dissipating a large amount of energy into the bulk water. As one of the photothermal materials in solar-driven interfacial evaporation system, wood has been widely applied due to its excellent properties, such as lower density, open micropores, capillary-induced hydrophilic nature, and low thermal conductivity. However, the complex processing technology and relatively low efficiency of wood-based photothermal materials limit their application. Herein, to solve these problems, solvothermal and immersion treatment methods by depositing tin sulfide and silver nanoparticles (AgNPs) have been demonstrated. The solar absorption rate of wood-SnS-AgNPs is higher than 98% in a wide wavelength range (200–2,500 nm). Results demonstrate that an evaporation rate of 1.53 kg m−2 h−1 and evaporation efficiency (90.12%) are achieved under 1-sun illumination (100 mW cm−2). The harsh environmental test indicates that the solar-driven interfacial evaporation system based on wood-SnS-AgNPs has excellent structural stability and purification ability of seawater.

Aqueous batteries based on iodine conversion chemistry have emerged as appealing electrochemical energy storage technologies due to iodine's intrinsic advantages of fast conversion kinetics, ideal redox potential, and high specific capacity. However, active iodine suffers from several limitations, such as poor thermal stability, inferior electrical conductivity, and polyiodide shuttling, which must be overcome before a real breakthrough and wide application. Over the past decades, researchers worldwide have dedicated substantial effort to tackling the above obstacles. In this review, a systematic summary of recent advances in aqueous iodine-based static batteries (AISBs) is presented. It begins with an introduction to iodine's fundamental physicochemical properties, particularly focusing on the analysis of iodine conversion chemistry, and discussing the corresponding challenges by category. Furthermore, the coping strategies in terms of cathode host selection, electrolyte optimization, separator engineering, and suitable anodes are in-deeply discussed, and the key parameters and work principles are analyzed. The final section shares the thoughts on the potential research opportunities and future directions in advancing AISBs.

Interfacial Modification of Multifunctional Organic Ammonium Salt for PEDOT:PSS-Based Inverted Perovskite Solar Cells 査読有り国際誌

担当区分：最終著者記述言語：英語掲載種別：研究論文（学術雑誌）

The performance of inverted perovskite solar cells (PSCs) is highly dependent on the surface properties of the hole-transport layers (HTLs). Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is one of the most widely used HTLs due to its excellent properties. However, some drawbacks severely limit its application in PSCs. Herein, multifunctional bulk organic ammonium salts (BOASs) are deposited onto PEDOT:PSS films and used for interfacial modifications. The BOASs-modified PEDOT:PSS has better energy-level alignment with perovskite (PVK) than PEDOT:PSS, resulting in the suppressed voltage loss of PSCs. Depositing BOASs on top of the PSS isolates moisture to inhibit the ionization of sulfonic acid groups, which is beneficial to reduce the acidity and corrosiveness of PEDOT:PSS. In addition, the interfacial modification of BOASs can effectively enlarge the surface energy of PEDOT:PSS films and improve the morphology of the PVK layer. Therefore, the open-circuit voltage and fill factor of the PSCs based on BOASs-modified PEDOT:PSS are simultaneously increased to a maximum of 1.03 V and 73%, respectively, resulting in a champion device efficiency of 18.37%. The unencapsulated PSCs based on BOASs-modified PEDOT:PSS remain more than 80% power conversion efficiency loss after 700 h of exposure to air.

Binary transition metal sulfides demonstrate abundant morphological features and high redox activity. By studying the relationship between different morphological characteristics of active materials and electrochemical performance, high-performance supercapacitors can be discovered. In this work, binary Ni3S2/MoS2 composites in situ grow on the current collector Ni foam via electrochemical deposition and subsequently hydrothermal reaction, then it was directly used as a binder-free electrode for supercapacitors. The micro-morphological evolution process was investigated by controlling the hydrothermal time from 3 to 12 h. The electrochemical characterization showed that Ni3S2/MoS2@NF-9 (hydrothermal reacted for 9 h) with fluffy and abundant nanopores demonstrated the highest specific capacity (341.7 C g−1 at 1 A g−1), best rate performance (50% capacity retention from 1 to 20 A g−1), and superior charge transfer ability compared with others. Ni3S2/MoS2@NF-9 was also used as a positive electrode to assemble Ni3S2/MoS2@NF-9//RGO hybrid supercapacitor (HSC), which displayed a specific capacity of 129.2 C g−1 at 0.5 A g−1 and specific energy of 26.9 Wh·kg−1 at 375 W kg−1.

Large-scale popularization and application make the role of lithium-ion batteries increasingly prominent and the requirements for energy density have increased significantly. The silicon-based material has ultra-high specific capacity, which is expected in the construction of next-generation high specific-energy batteries. In order to improve conductivity and maintain structural stability of the silicon anode in application, and further improve the energy density of the lithium-ion battery, we designed and synthesized carbon-coated porous silicon structures using diatomite and polysaccharides as raw materials. The electrode materials constructed of diatomite exhibit porous structures, which can provide fast transport channels for lithium ions, and effectively release the stress caused by volume expansion during cycling. At the same time, the electrical conductivity of the materials has been significantly improved by compounding with biomass carbon, so the batteries exhibit stable electrochemical performance. We systematically studied the effect of different contents of biomass carbon on the Li2MnSiO4/C cathode, and the results showed that the carbon content of 20% exhibited the best electrochemical performance. At a current density of 0.05C, the capacity close to 150 mAh g−1 can be obtained after 50 cycles, which is more than three times that of without biomass carbon. The silicon-based anode composited with biomass carbon also showed excellent cycle stability; it could still have a specific capacity of 1063 mAh g−1 after 100 cycles at the current density of 0.1 A g−1. This study sheds light on a way of synthesizing high specific-capacity electrode materials of the lithium-ion battery from natural raw materials.

The improvement of solid-state batteries (SSBs) in terms of safety performance and energy density has an unusual significance for it to apply to power batteries, and the interface matching of solid-state electrolytes and adapted electrode materials has become the key. Due to poor electrode-electrolyte interface contact in SSBs which could result in low ionic conductivity, we designed a 3D integrated electrode constructed from a Cu2MoS4 electrode grown in situ on the surface of copper foam with a polymer-in-salt solid electrolyte based on PVDF-HFP. The ion clusters formed by NaPF6 near the PVDF-HFP network structure can effectively shorten the Na+ transport path, and then adding 1-(4-cyanophenyl)-guanidine can also provide more ion transport routes by forming coordination bonds. The polymer electrolyte exhibited excellent ionic conductivity (1.67×10−5 S cm−1 at room temperature) and electrochemical stability (5.6 V vs Na|Na+). At the same time, it showed excellent stability during the cycle performance test of the symmetrical batteries, compared with the liquid electrolytes, the polymer-in-salt solid electrolytes were not short circuit under the same test conditions, indicating that the polymer-in-salt solid electrolytes can effectively inhibit the growth of Na dendrites. This 3D integrated electrode exhibited excellent interface-contact compatibility, mechanical stability, and electrochemical performance closed to that of liquid electrolytes and even outperformed liquid electrolytes at a high rate cycle.

Carbon-based perovskite solar cells (C-PSCs) have the characteristics of a simplified device architecture, low-cost and excellent long-term stability, thus they demonstrate a significant commercial potential. However, the efficiency is not very ideal due to the lack of the hole transport layer, resulting in insufficient carrier collection and transport. In this study, we introduce an organic material, 2-(trifluoromethylthio)aniline (TMTA), to improve the performance and stability of the devices. Benefiting from strong interactions between the functional groups and perovskite, incorporation of the interface modification materials can improve the perovskite quality, decrease the defects, and adjust the energy level between perovskite and carbon electrode. The champion devices with TMTA achieve a power conversion efficiency (PCE) of 15.31%. Meanwhile, the long-term stability after the TMTA modification is also improved. This study supplies a simple idea for improving the performance of C-PSCs.

Many experimental studies have been conducted in this field; however, theoretical calculation, which offers an effective and low-cost approach to designing and choosing appropriate ILs, has rarely been applied. With the rapid development of computational chemistry, calculation, modeling, and simulation of chemical systems have been an important technique to understand and predict behaviors at the molecular level. Combining computational chemistry with experimental study has emerged as a highly efficient methodology for accelerating the development of traditional experimental studies. In this work, the chemical properties of pyridine-base ILs are investigated by density functional theory for the prediction of their potential adsorption performance. Molecular dynamic (MD) simulations of the interfacial behavior between the designed ILs and Ni and Mo surfaces were carried out to evaluate the dynamic processes. In this way, potential ILs as high performance electrolytes and additives for electrodeposition can be chosen on a theoretical basis. The study can be regarded as providing theoretical guidance for choosing appropriate electrolytes or additives for electrodeposition as well as for understanding the interfacial behavior between ILs and metal surfaces.

Sodium-ion batteries (SIBs) have been rapidly developed as an effective replacement or supplement for lithium-ion batteries (LIBs) due to the high natural abundance and low cost of sodium resources. Sodium super ion conductor (NASICON)-type materials have high ionic conductivity and excellent structural stability, making them one of the potential electrode candidates for SIBs. V(vanadium)-based polyanionic compounds have been the most extensively studied NASICON-structure materials. However, the environmental pollution and high-cost issues of V-based materials demand serious consideration. Currently, V-free NASICON-type electrodes have garnered a lot of attention. In this review, V-free NASICON electrodes for SIBs are first systematically summarized. The latest advances in related cathode/anode materials with various metal redox couples are classified and introduced in terms of their preparation method, structural characteristics, and electrochemical performance. Moreover, the performance improvement strategies and future prospects are discussed. It is expected that the insights may inspire future research into the development of more clean, efficient, and low-cost electrodes for SIBs.
