Two dimensional (2D) perovskite materials, are more stable than 3D perovskite materials, which could solve the stability issue of perovskite solar cells (PSCs). However, the photovoltaic conversion efficiency (PCE) of PSCs based on 2D perovskite materials was low, due to the high dielectric and quantum confinement of 2D perovskite. In this work, we propose a solvent-assisted method to prepare 2D perovskite films, where the solvent was distributed in a gradient. Therefore, the top-down crystallization process of 2D perovskite can be accurately controlled. The PCE of PSCs fabricated by the solvent-assisted method was enhanced by 48%, compared with the control device. For the packaged devices, the stability test demonstrated that 94% of the initial PCE was still maintained after 1500 hours of storage (25 °C, RH 40%). After carefully analyzing the photophysical process of the carriers in the PSCs based on 2D perovskite, the enhanced carrier transfer mechanism of the solvent-assisted method has been proposed.

The undesired energy level alignment and charge recombination at the perovskite/carbon electrode interface limit the application of carbon-based perovskite solar cells (C-PSCs). The incorporation of hole transport materials, CuSCN, is an effective strategy to solve this issue. However, the mismatched crystal structure and lattice between the perovskite layer (cubic crystal) and CuSCN layer (hexagonal crystal) lead to a charge transport barrier due to the gaps at the heterogeneous interface. Herein, the interfacial engineering designed on CuSCN has been carried out, which not only improves the quality of perovskite film but also reduces the defects, enhances the interfacial connection, and ensures rapid charge extraction and transfer. After key parameter adjustment, both high efficiency (15.81%) and good stability of C-PSCs have been obtained. After storage for 2,000 h at ambient air environment, devices without any encapsulation could maintain 93% of their initial efficiency. The thermal stability test shows that the encapsulated devices retain 83% of their initial efficiency after storage for 300 h in dry air at 85 °C. Deep insight and mechanisms have been proposed in this interfacial engineering design for improving the efficiency and stability of C-PSCs.

Silicon-flexible carbon composites can achieve binder-free application and solve the problem of silicon expansion during cycles. The effective loading and dispersion of silicon onto carbon play an important role in improving the performance of anode materials. Herein, surface engineering of the hole-opening process was successfully achieved before the deposition of silicon. This resulted in fine holes on the carbon cloth, increasing the specific surface area to provide abundant confined spaces for dispersing nano-silicon. A composite structure was formed and structurally optimized by depositing an ultra-thin silicon layer in the holes of mesoporous carbon fiber cloth (DTSi/CC), improving the conductivity of the material, increasing the migration rate of lithium ions, and inhibiting the volume expansion of the anode material during the cycles. At 100 mA g-1, the fabricated half-cells achieved a reversible capacity of 1457 mA h g-1and retained 70.9% initial capacity after 100 cycles. Even when the current density was increased to 1.0 A g-1, they boasted a capacity of 1037 mA h g-1and had 76.8% capacity retention after 500 cycles. Free of binders and conductive additives, the DTSi/CC composite was directly used as the anode, exhibiting superior properties with high reversible specific capacity, excellent cyclic performance, and good rate capability. This study provides a straightforward, effective route to obtain high-performance silicon-based anode materials for lithium-ion batteries.

With rapid economic development, utilization of energy storage is increasingly important. Carbon materials derived from biomass are widely applied in energy storage systems due to their inexpensive and environmentally friendly nature. Compared to other advanced anode materials that have been explored, biomass carbon materials have high specific surface areas, adjustable porous structures, and heteroatoms that facilitate ion transfer and diffusion. To date, a series of porous biomass-derived carbon materials prepared through various methods have been used as anode electrodes of secondary batteries which greatly promoted their capacities. In this paper, we summarize the morphology and pore structure of biomass-derived materials from different precursors and discuss the electrochemical performance of secondary batteries (LIBs, SIBs, KIBs and ASSLMBs) equipped with biomass-derived carbon materials including monomers and composites as anode electrodes. Current research challenges along with future prospects for carbon-based electrode materials to improve secondary battery energy storage performance are emphasized.

In recent decades, catalytic reduction of CO2 is a hot topic in the research field of electrocatalysis. Copper is the only metal catalyst capable of producing multiple carbon (C2+) products in electrocatalytic CO2 reduction (ECR), however, there are still many challenges such as low selectivity, serious hydrogen evolution (HER) and poor stability. So far, various synthesis methods have been developed for Cu-based catalysts. Compared with ordinary chemical synthesis, electrochemical method has the advantages of simple process, controllable conditions, good safety and eco-friendly. In this review, the recent progress in synthesizing different types of Cu-based catalysts by means of the electrochemical method are comprehensively reviewed. The engineering strategies and the effects of the key preparation conditions on the catalytic performance of CO2 electroreduction for C2+ products are discussed in details. Besides, copper-based catalysts synthesized by electrochemical methods combined with the ordinary methods (wet chemical methods, plasma activated methods and other methods) were also outlined. Finally, the development potential of electrochemical synthesis for Cu-based catalysts are recommended, which provides a direction for the future development of Cu-based catalysts with low cost and high ECR performance.

Organic semiconductor materials are widely used in the field of organic electronic devices due to their wide variety, low price, and light weight. However, their developments are still restrained by their low stability and carrier mobility. Density functional theory (DFT) was used to study the influence of doped oxygen group elements (O, S, Se, and Te) on the properties of organic semiconductor materials (seven-membered benzothiophene,o-pentacene, thiophene derivatives, and pentacene) in this paper. Based on the calculation ofEHOMO,ELUMO, ΔE, and total energy, the performances of organic semiconductor materials without and with doped elements were compared, and it was found that the doping of multi-element Te makes the material have high stability and potential high mobility. For these studied organic semiconductor materials, when the atoms of the doped site change in the order of O, S, Se, and Te, the carrier mobility gradually increases, and the molecules show a tendency of stability. In this paper, promising doping elements and doping methods for these studied molecules are determined through calculations and screening out suitable materials more efficiently and economically without a large amount of repetitive experimental work, which may provide a theoretical basis and guidance for preparing high-performance organic semiconductor materials.

In the family of inorganic perovskite solar cells (PSCs), CsPbBr has attracted widespread attention due to its excellent stability under high humidity and high temperature conditions. However, power conversion efficiency (PCE) improvement of CsPbBr -based PSCs is markedly limited by the large optical absorption loss coming from the wide band gap and serious charge recombination at interfaces and/or within the perovskite film. In this work, using density functional theory calculations, we systemically studied the electronic properties of niobium (Nb)-doped CsPbBr with different concentration ratios. As a result, it is found that doped CsPbBr compounds are metallic at high Nb doping concentration but semiconducting at low Nb doping concentration. The calculated electronic density of states shows that the conduction band is predominantly constructed of doped Nb. These characteristics make them very suitable for solar cell and energy storage applications. 3 3 3 3

All-inorganic perovskite materials, typically CsPbI Br, have received widespread attention owing to their outstanding thermal stability than that of organic/inorganic hybrid counterparts. However, the power conversion efficiency (PCE) of CsPbI Br perovskite solar cell (PSC) is far lower than its theoretical value. In this study, to further improve the PCE, a sulfur-rich small molecule material (delta-2:2-bis (1,3-dithiazole)), is used to modify the interface between CsPbI Br and carbon electrode. Encouragingly, the carbon-based CsPbI Br PSCs achieve a high PCE of 13.78% than the control of 10.40%, which is the best performance of carbon-based CsPbI Br PSC among the literature report at present. The remarkable reduction of defect density and suppression recombination should be responsible for the PCE improvement. This work proposes a simple and effective strategy to enhance the efficiency of all-inorganic carbon-based CsPbI Br PSCs. 2 2 2 2 2 2

Metal corrosion is an important technical problem often encountered in industrial production in various fields. One of the efficient and economical methods to effectively block corrosion is to add a corrosion inhibitor, which forms a protective film on the metal surface. Accordingly, environmentally friendly organic corrosion inhibitors have become research hotspots in recent years. Among them, polyorganic substances have been proved to be effective corrosion inhibitors; however, research on this topic is still scarce. In this study, (poly) ethylene glycol and (poly) acrylamide are investigated as polyorganic inhibitors by density functional theory and molecular dynamic simulation, and the effect of the degree of polymerization (DP) on the adsorption behavior on metal surfaces is theoretically analyzed. On the basis of a comprehensive evaluation of their stability and adsorption energy, the optimal DPs of these two inhibitors are determined. This work may provide a theoretical basis and guidance for further research of corrosion inhibitor.

The decent power conversion efficiency (~20%), ultra-low cost, and 1-year stability make carbon-based perovskite solar cells (C-PSCs) one of the most promising candidates for commercialization in the field of perovskite photovoltaics. However, the stability of C-PSCs still lags behind that of the commercialized silicon and thin-film photovoltaics. Although there have been many reviews of the long-term stability of perovskite solar cells (PSCs), none has specifically focused on the long-term stability of C-PSCs. Herein, we summarize the environmental risks and strategies for ensuring the long-term stability of C-PSCs, highlighting also the various contributions of our research group. The most important factors affecting long-term stability are analyzed according to the environmental risks (i.e. moisture, oxygen, light, and thermal stress) of device degradation. The proposed strategies chiefly center around improving the intrinsic stability and strengthening encapsulation. In our conclusions, we also present an outlook on future work concerning stability improvement and commercial development of C-PSCs. Our work provides a clear guideline for future research on C-PSCs.

Electrocatalysts are the cores of many electrochemical reactions including hydrogen evolution reaction (HER), oxygen evolution reaction (OER), oxygen reduction reaction (ORR), nitrogen reduction reaction (NRR), and CO2 reduction reaction (CO2RR). Recent advances in research have demonstrated the potentials of molybdenum carbide-based catalysts for these reactions arising out of their unique electronic structure and physicochemical properties. In this review, we systematically summarize the recent advances of molybdenum carbide-based catalysts in these electrochemical processes. The corresponding synthesis strategies, structure and electrocatalytic performance of the catalysts are discussed and the relationships of the process-structure-property are highlighted. In addition, the catalytic mechanisms are analyzed based on the structure characterization and theoretical calculations results. Finally, the existing challenges and future perspectives are put forward for further development of molybdenum carbide-based catalysts.

Metal-free catalysts for the CO2 reduction reaction (CO2RR) is a research hotspot to enhance CO2 utilization as a way to counteract global warming. Nitrogen-doped graphene attracts attention because of the abundance of nitrogen and promising catalytic performance of graphene. In this work, we investigated various N-doped configurations and their corresponding catalytic abilities for CO2RR to ethanol via spin-polarized density functional theory (DFT) computations. The final results indicate that site 43 of binary-N-doped graphene had high CO2RR activity, stable adsorption of reactants, and good activation of CO2. The catalysis process demonstrated features of low free energy barriers in the rising stage and obvious facilitation of the potential-limiting step. Compared with a catalyst-free process, it can effectively improve the reaction activity. The results provide theoretical guidance for the design and preparation of high-performance CO2RR catalysts.

Temporally intermittent and spatially dispersed renewable energy sources strongly call for large-scale energy storage devices. Aqueous aluminum-ion batteries show great potential for application due to their safety and low cost. Thus far, however, the ideal full-battery configuration is beyond the scope due to shortcomings with regards to suitable anode and cathode materials. Herein, we report a pioneering aqueous aluminum-ion battery system consisting of a Prussian white cathode, 1 M Al2(SO4)3 aqueous electrolyte, and an organic 9,10-anthraquinone anode. The oxidation capability of the Prussian white cathode during the first charging allows for the fabrication of the full battery without pre-inserting aluminum ions, thus making the rocking-chair-type battery feasible. Importantly, the open-framework structure of the Prussian white and distinct enolization charge storage mechanism of 9,10-anthraquinone ensure fast reaction kinetics. The full battery exhibits cycling stability with a capacity retention of 89.1% over 100 cycles at 500 mA g−1, finishing a cycle in about 10 min. This work provides a pathway for developing rechargeable aqueous aluminum-ion batteries.

The electrochemical conversion of nitrogen (N ) to ammonia (NH ) under ambient conditions is a highly promising alternative to the energy-intensive Haber-Bosch process. However, it suffers from poor yields and selectivity because of the lack of efficient catalysts. Herein, we prepared an economical and eco-friendly efficient biochar catalyst from peanut shells and achieved a high ammonia yield (2.32 μmol h cm ) and selectivity (faradaic efficiency of 26.97%) over 12 h of stable operation. The results of density functional theory calculations illustrate that association pathways are more likely to occur on the active sites Bio-N4, Bio-O37, and Bio-S58, while dissociation pathways always occurred on the active sites Bio-O15, Bio-O21, and Bio-O52. Furthermore, Bio-O21 is the most promising active site for the NRR following the NNH dissociation pathway with a lower reaction barrier. The preferable adsorption of N , desorption of NH , and suppression of the HER demonstrated the peanut shell-derived material as a more promising catalyst for the NRR. 2 3 2 2 3 −1 −2

The conversion of nitrogen into ammonia is crucial for human activities. The electrochemical synthesis of ammonia from nitrogen and water is a green process with great application prospects; to this end, much effort has been made to improve the catalytic activity and selectivity. Here, a Co-based metal-organic framework (MOF), that is, zeolitic imidazolate framework-67 (ZIF-67), supported on a Ti3C2 MXene (defined as ZIF-67@Ti3C2) was prepared via in situ growth. Due to the high porosity and large active surface area of the MOF and the superior conductivity of the Ti3C2 MXene, the composite could efficiently synthesize ammonia electrochemically. In particular, the prepared ZIF-67@Ti3C2 catalyst exhibited an excellent NH3 yield (6.52 μmol h-1 cm-2), significantly higher than those achieved by Ti3C2 and ZIF-67 (2.77 and 1.61 μmol h-1 cm-2, respectively) alone, and good Faraday efficiency (20.2%) at -0.4 V (vs. the reversible hydrogen electrode). This study not only expands the application of the MXene family in the electrochemical nitrogen reduction reaction but also provides ideas for the development of high-performance electrocatalysts for NRR.

Benefiting from the high electrochemical surface area brought by the 2D nanosheet structure, MoS has received great research attention for the hydrogen evolution reaction (HER). Recently, it has been demonstrated that by constructing a transitional metal sulfide-MoS heterostructure, the HER performance of the MoS -based catalysts can be further improved. It is even possible to obtain bifunctional catalysts for both HER and oxygen evolution reaction (OER) due to the synergistic effect of the different components in the composite, the electronic effect to enable an efficient electron transfer and appropriate binding energy for the intermediates of the electrocatalytic reactions, and the surface defects on the interface of the heterostructures. Herein, we review the recent progress on the construction of the transitional metal sulfide-MoS heterostructure for water splitting based on non-self-supporting and self-supporting catalysts. The surface and interface parameters of the heterostructures are discussed in detail to reveal the key roles of the hybrid structures for energy conversion. We also pay special attention to the theoretical simulations based on first principles to clarify the relationships between the electrochemical performance and structure parameters. Finally, the prospects and challenges of the transition metal sulfide-MoS heterostructures for water splitting in the future are proposed to prompt the reasonable design of transition metal sulfide-MoS heterostructures for full water splitting. 2 2 2 2 2 2

Ammonia (NH3) is recognized as a chemical substance that is very important for the development of human society. At present, the traditional industrial synthetic ammonia process is Haber-Bosch, which has some shortcomings such as low conversion rate, high energy consumption and greenhouse gas emission. Therefore, the search for new synthetic ammonia methods has attracted the attention of many scientific researchers. In this work, we use density functional theory (DFT) to explore vacancy and heteroatom (N, S) doped defective carbon materials suitable for catalyzing nitrogen reduction reaction (NRR). The introduction of vacancy defect, N or S atom doping graphene can improve the reactivity of graphene. In addition, the high activity sites of defective graphene mainly distribute on the carbon atoms at the upper left edge, the right edge and the lower edge. The research results theoretically determine the effect of different doping methods, doping positions and quantities on material properties, and provide theoretical basis and guidance for exploring new carbon catalysts.

Abstract: Rechargeable batteries, which are used for renewable energy storage, have paved the way for reducing the enormous pressure of the energy crisis and environmental pollution. Recently, promising electrode materials with high energy and power density and favorable electrochemical performance for energy conversion and storage have been developed to meet the ever-growing demand for renewable power for electric vehicles or grid applications. MXenes, which constitute an impressive two-dimensional transition metal carbide/carbonitride family, exhibit great energy storage potential based on their ideal specific surface area, excellent electrical conductivity, and superior chemical durability in batteries. The recent advances in MXenes and their composites for metal-sulfur batteries (specifically lithium-sulfur and sodium-sulfur batteries) and metal-air batteries (specifically lithium-air and zinc-air batteries) are comprehensively and systematically summarized in this review. Furthermore, the performance management strategies, next-stage research prospects, and remaining practical challenges for MXene-based materials in battery applications are discussed in detail. This review may provide some guidance for the development and application of MXene-based electrode materials in renewable electrochemical energy storage.

Recent Progress in Perovskite Solar Cells Modified by Sulfur Compounds 査読有り

記述言語：英語掲載種別：記事・総説・解説・論説等（学術雑誌）

In the past decade, organic–inorganic hybrid perovskite solar cells (PSCs) have begun to be increasingly studied worldwide owing to the superior properties of perovskite material. However, some issues have delayed their commercialization, such as their long-term stability, cost reduction, scale-up ability, and efficiency. The introduction of sulfur to PSCs can relieve the above issues because sulfur can passivate interfacial trap states, suppress charge recombination, and inhibit ion migration, thereby enhancing the stability of PSCs. Furthermore, Pb-S bonds provide new channels for carrier extraction. Herein, the sulfur-based compounds utilized in PSCs are summarized and classified according to their functions in the different layers of PSCs. The results indicate that these sulfur-based compounds have efficiently promoted the commercialization of PSCs. It is hoped that this review can help others understand the intrinsic phenomena of sulfur-based PSCs and motivate additional investigations.
