Summary: Efficient and low cost catalysts for hydrogen production are essential for the future hydrogen economy. This study demonstrates a method to transform non-active material into highly active catalysts for the hydrolysis of ammonia borane (AB) by forming tiny clusters on graphene oxide (GO) with strong cluster-support interaction. By adjusting the electronic structure of the clusters, the catalytic activity can be greatly enhanced. The final bimetallic CoCu catalyst on GO exhibits high catalytic performance for AB hydrolysis.

Summary: In this study, a trace Ru-based RuCo bimetallic alloy catalyst was prepared through a simple impregnation reduction approach and the hydrolysis catalysis of ammonia borane (AB). The activity of the catalyst is mainly determined by the composition of Ru and Co metals. The high catalytic activity of Ru0.075Co0.925/NPC can be attributed to the active cluster ensemble effect of the bimetallic RuCo alloy, which exhibits the random stacking of rigid geometry and more d-electron layers without filling, leading to strange catalytic properties. Additionally, the co-alloying effect between Ru and Co NPs improves the hydrolysis performance of AB. This experimental study provides a promising approach for high catalytic activity and the potential of hydrogen production from chemical storage materials.

Summary: Incorporating g-C3N4 with transition metal phosphides has the potential to create a low-cost and robust co-catalyst for hydrogen evolution. The ammonia borane hydrolysis method efficiently releases H2 in the presence of a catalyst under ambient conditions. A Ni2P/C3N4 catalyst is synthesized using a hydrothermal method and low-temperature phosphidation, and optimization reveals that the catalyst with 6.5% Ni content performs the best for H2 release. Furthermore, loading 2% Pt nanoparticles over Ni2P/C3N4 improves activity 5.7-fold and enhances charge transfer.

Summary: In this study, zeolitic imidazolate framework-8 (ZIF-8) was grown uniformly on Cu nanosheets, and carbon-coated CuZn alloy nanosheets were prepared by calcination under H-2/Ar atmosphere. The CuZn@C nanosheets acted as zincophilic sites to uniformly absorb Zn ions and inhibit the formation of Zn dendrites. They also prevented the direct contact between zinc anode and electrolyte, preventing side reactions. The CuZn@C nanosheets exhibited excellent zinc plating/exfoliation performance and long cycle life.

Summary: Metal halide perovskites (MHPs) have shown great potential as a new generation of photocatalysts due to their tunable band gap, wide visible light absorption range, and fast carrier transfer. However, their poor stability under water, oxygen, and high temperatures, as well as the recombination of photogenerated charges and weak oxidation activity, pose challenges for their development.

Summary: By phosphidation of metal-organic framework (MOF) nanofiber (NF) composites, bifunctional cobalt phosphide NFs (CoP NFs) were successfully fabricated and used as electrocatalysts for water splitting, showing a large catalytic surface area. A series of 1D nanostructures including Co3O4 NFs and carbon NFs immobilized with CoP or Co nanoparticles were also synthesized and investigated. The catalytic performances of CoP NFs could be improved by modulating Cu-related species, and the Cu-doped CoP NFs showed comparable performance to commercial noble-metal catalysts for both oxygen and hydrogen evolutions.

Summary: The growth of zeolitic imidazolate framework-8 (ZIF-8) on CuO nanosheets (NSs) and the preparation of carbon-coated CuZn alloy NSs (CuZn@C NSs) under H-2/Ar atmosphere have been used to tackle the issues hindering the development of aqueous zinc-ion batteries (AZIBs). The Cu-Zn and Zn-N bonds in CuZn@C NSs act as zincophilic sites to uniformly absorb Zn ions and prevent the formation of Zn dendrites, while also hindering the side reactions between the zinc anode and electrolyte. The CuZn@C NSs exhibited excellent zinc plating/exfoliation performance, long cycle life, and high capacity retention when used as anodes in CuZn@C/V2O5 full cells.
