Summary: In this study, composite catalysts of MoS2 and MoO2 were prepared using a one-step hydrothermal method and used for photocatalytic hydrogen production. The 2H-MoS2/MoO2 composite catalyst showed the best performance with 48% MoO2 content, achieving a hydrogen yield of 960 mu mol/h and an improved selectivity by 22%. The excellent performance of the composite catalyst was attributed to the formation of a heterogeneous structure between MoS2 and MoO2, improving the migration of photogenerated carriers and reducing the possibilities of recombination.

Summary: The photocatalytic activity of iron-grafted mesoporous Pt/TiO2 catalysts for hydrogen production from water-ethanol mixtures was investigated. Results showed that Fe is primarily located on the catalyst surfaces as Fe2O3 and does not dope the TiO2 structure. The catalyst with the lowest iron content exhibited the highest activity for ethanol dehydrogenation, attributed to the higher surface dispersion of Fe and efficient formation of a surface heterojunction between Fe2O3 and TiO2 that favors charge separation.

Summary: Creating flexible batteries for wearable and portable electronics is crucial. The traditional DMFC cannot be used in flexible devices due to its mechanical assembly and lack of flexibility. This study presents a flexible all-solid-state DMFC using a flexible membrane electrode assembly with TiC-modified carbon cloth as a supporting layer. Additionally, the solid methanol fuels used in this DMFC have the advantages of being small, light, and having high energy density. The flexible all-solid-state DMFC has a high power density of 14.06 mW cm(-2) and negligible voltage loss after 50 bends at 60 degrees. Its energy density of 777.78 Wh kg(-1) surpasses flexible lithium-ion batteries, making it advantageous for commercializing flexible electronic products.

Summary: Aqueous zinc-ion batteries (ZIBs) have potential as highly promising rechargeable batteries due to their safety, low costs, and environmental advantages. Challenges associated with aqueous electrolytes have hindered their widespread utilization, but recent advances in solid-state electrolyte research show promising potential. Solid-state electrolytes offer flexibility and new chemistry, making them suitable for wearable electronic devices and multifunctional settings. However, the development of solid-state electrolytes is still in its early stages, and closing the existing gap is crucial before solid-state ZIBs become practical.
