© 2015 Elsevier B.V. All rights reserved.Cu(I), Pb(II), Sb(III), Zn(II), Cd(II), In(III), Ga(III) xanthates were synthesized and characterized by 1H NMR, 13C NMR, infrared spectroscopy and elemental analysis. The final product of decomposition of metal xanthates at 200 °C subjected to XRD and EDS analysis, confirmed generation of metal sulfides. The curing behavior was analyzed by performing curing time investigation of epoxy composite as a function of temperature employing 5% metal xanthates as catalysts. None of the metal xanthates demonstrated any significant curing of epoxy composite prior to 150 °C proving their latent curing potency. Ga(III) xanthate exhibited comparatively the most effective catalytic property. Thermogravimetric analysis utilized to examine the thermal behavior of metal xanthates indicated, metal xanthates which are air-stable at ambient temperatures undergo latent decomposition upon thermal annealing. The order of curing time at a given temperature and the trend of decomposition temperature of metal xanthate under consideration was observed to be similar. XRD and EDS study of epoxy composite consisting of metal xanthates cured by thermal annealing illustrated generation of metal sulfide in-situ in the matrix. It was presumed that the phenomena of metal xanthates under investigation yielding corresponding in-situ metal sulfides in the epoxy composite upon thermal annealing in a latent fashion is responsible for exhibiting latent curing catalytic activity.

© 2015 American Chemical Society.In perovskite solar cells (PSCs), issues of compatibility between the photoabsorber and the cell architecture arise. In this work, we systematically demonstrated the characteristics of PSCs with an organometal halide, CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3</inf> or CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3-x</inf>Cl<inf>x</inf>, in a planar or mesoporous architecture, and the dependence of the cell photovoltaic performance on the architecture was illustrated in detail. In addition to the inherent photoelectric characteristics, CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3</inf> and CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3-x</inf>Cl<inf>x</inf> also differ in other aspects, such as light absorption, crystallinity, surface coverage, and dissociation of the photogenerated electrons. For PSCs with CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3</inf>, the mesoporous ones gave high power conversion efficiencies (PCE) of up to 14.05%, which is much higher than those of the planar ones (up to 6.76%). For PSCs with CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3-x</inf>Cl<inf>x</inf>, the planar and mesoporous devices exhibited PCEs of up to 12.67% and 7.87%, respectively, quite in contrast with the case of CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3</inf>.

Copyright © 2014 John Wiley & Sons, Ltd.Transparent conductive oxide-less (TCO-less) dye-sensitized solar cells (DSSCs) have been fabricated and characterized using nanoporous TiO<inf>2</inf>-coated stainless steel metal mesh as flexible photoanode and cobalt bipyridyl complex (Co(bpy))-based one electron redox shuttle electrolyte. Attempts have been made towards enhancing the efficiency of TCO-less DSSCs to match with their TCO-based DSSC counterparts. It has been found that surface protection of metal mesh is highly required for enhancing the efficiency of TCO-less DSSCs specially using cobalt electrolytes as confirmed by dark current-voltage characteristics. Photocurrent action spectra clearly reveal that TCO-based DSSCs using (Co(bpy)) electrolyte exhibits photon harvesting (incident photon to current conversion efficiency (IPCE) 52%) in the 370-450 nm wavelength region as compared to photon harvesting at peak absorption of the dye (IPCE 56% at 550 nm), which is almost the same (IPCE 47%) in the 400-610 nm wavelength region for TCO-less DSSCs. Under similar experimental conditions, replacing indoline dye D-205 to porphyrin-based dye YD2-o-C8 led to the enhancement in the photoconversion efficiency from 3.33% to 4.84% under simulated solar irradiation.

© Editorial office of Acta Physico-Chimica Sinica.Hybrid organic-inorganic lead halide perovskite solar cells (PSCs) have recently undergone rapid progress and exhibit high photoelectric conversion efficiencies of up to 19.3%. As light-absorber in PSCs, the hybrid organic-inorganic lead halide perovskite cannot be used in large-scale applications because of its high Pb content. In this work, we replaced some Pb with Sr to synthesize a novel perovskite CH3NH3SrxPb(1-x)I3and used it as a light-absorber in PSCs. Compared with CH3NH3PbI3, CH3NH3Sr0.3Pb0.7I3is a better light-absorber but the corresponding photovoltaic performance in PSCs decreased obviously.

Relationship between diffusion of Co3+/Co2+ redox species in nanopores of porous titania stained with dye molecules, dye molecular structures, and photovoltaic performances 査読有り

記述言語：英語掲載種別：研究論文（学術雑誌）

© 2015 The Royal Society of Chemistry.Diffusion of Co2+ and Co3+ in nanopores of porous titania stained with various dyes were evaluated and were compared with those of I-, and I3-. Diffusion of Co3+ in the bare nanopore was slower than that of I3-. Dyes adsorbed on the wall of nanopores affected these diffusion coefficients remarkably. The Co3+ diffusion in nanopores became faster when the nanopore wall was covered with dyes with long alkyl groups, probably because the long alkyl groups suppress the interaction between TiO2 surface and Co3+. Higher open circuit voltage (Voc) was obtained for the DSSC with fast Co3+ diffusion in nanopores because the fast diffusion suppresses the charge recombination between electrons in titania and Co3+ remaining in the nanopores. The fast diffusion in nanopores was applied to thin nanoparticle spacer (th: 5 μm) of DSSCs. After nanoparticle spacer was stained with dyes with long alkyl groups, the efficiency drastically increased from 2.8% to 5.3%.

Atomically thin MoSe<inf>2</inf>/graphene and WSe<inf>2</inf>/graphene nanosheets for the highly efficient oxygen reduction reaction 査読有り

© 2015 The Royal Society of Chemistry.As a conceptually new class of 2D materials, inorganic graphene analogue (IGA) ultrathin nanosheets perform an increasingly vital function in various electronic devices. However, the relatively low electrical conductivity of IGA ultrathin nanosheets severely hampers their application as electrode materials in devices. Through in situ synthesis, we report the combination of inorganic graphene and graphene into atomically thin nanosheets as efficient electrocatalysts for the oxygen reduction reaction (ORR). Benefitting from the advantages of both IGAs and reduced graphene oxide, the g-MoSe2 and g-WSe2 nanocomposites showed excellent ORR activity associated with a number of exchanged electrons close to four, which corresponded to the complete reduction of oxygen into water. In particular, the two electrocatalysts exhibited a positive onset potential of -0.02 V (close to that of Pt/C, 0.02 V) and a high kinetic current density (JK) of 10.22 mA cm-2 for g-MoSe2 and 10.77 mA cm-2 for g-WSe2 at -0.20 V. Compared with commercial Pt/C, these catalysts possess outstanding long-term durability and fuel crossover resistance capacity in alkaline media. Therefore, nanocomposites of inorganic graphene and graphene can be developed into low-cost and efficient alternatives (to the noble metal Pt) to be used as cathodic electrodes in fuel cells.

This system enables the investigation of the electrocatalytic behavior of a single-atom catalyst (SAC). Compared with conventional Pt CEs, the SAC-based CEs exhibit better reversibility as indicated by the peak-to-peak separation (Epp). A high degree of atom utilization is demonstrated.

© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Dye-sensitized solar cells (DSSCs) have attracted widespread attention in recent years as potential cost-effective alternatives to silicon-based and thin-film solar cells. Within typical DSSCs, the counter electrode (CE) is vital to collect electrons from the external circuit and catalyze the I3- reduction in the electrolyte. Careful design of the CEs can improve the catalytic activity and chemical stability associated with the liquid redox electrolyte used in most cells. In this Progress Report, advances made by our groups in the development of CEs for DSSCs are reviewed, highlighting important contributions that promise low-cost, efficient, and robust DSSC systems. Specifically, we focus on the design of novel Pt-free CE catalytic materials, including design ideas, fabrication approaches, characterization techniques, first-principle density functional theory (DFT) calculations, ab-initio Car-Parrinello molecular dynamics (CPMD) simulations, and stability evaluations, that serve as practical alternatives to conventional noble metal Pt electrodes. We stress the merits and demerits of well-designed Pt-free CEs, such as carbon materials, conductive polymers, transition metal compounds (TMCs) and their corresponding hybrids. Also, the prospects and challenges of alternative Pt catalysts for their applications in new-type DSSCs and other catalytic fields are discussed.

HOCO-R-NH3+I monolayer working as an anchor for perovskite (CH3NH3PbI3 (abbreviation: PEROVI3)) was inserted between the surface of porous metal oxide (titania or alumina) and the PEROVI3. Power conversion efficiency (PCE) of PEROVI3 solar cells increased from 8% to 10% after the HOCO-R-NH3+I- monolayer was inserted. Moreover, PCE of 12% was achieved for cells fabricated at optimized conditions. This increase in the efficiency was explained by retardation of charge recombination, and better PEROVI3 crystal growth, which improves PEROVI3 network on these porous metal oxides. It was proved that PEROVI3 crystal growth can be controlled by HOCO-R-NH3+I- on these porous metal oxides. © 2014 American Chemical Society.

Recent progress of counter electrode catalysts in dye-sensitized solar cells 査読有り

Wu M., Ma T., Ma T.

Journal of Physical Chemistry C 118 ( 30 ) 16727 - 16742 2014年07月

記述言語：英語掲載種別：研究論文（学術雑誌）

To realize long-term developments and practical application of the dye-sensitized solar cells (DSCs) requires a robust increase of the power conversion efficiency (PCE) and a significant decrease of the production cost. Fortunately, a new record PCE value of 12.3% was achieved by using cobalt-based redox couples combined with organic dye. Evidently, dye design is the key path to improve the PCE, while developing low cost counter electrode (CE) catalysts is one of the promising paths to reduce the production cost of DSCs by replacing the expensive Pt CE. In this article, we review the recent progress of CE catalysts involving Pt, carbon materials, inorganic materials, multiple compounds, polymers, and composites. We discuss the advantages and disadvantages of each catalyst and put forward ideas for designing new CE catalysts in future research for DSCs and other application fields. © 2014 American Chemical Society.
