Summary: Designing high-performance catalysts for electrocatalytic hydrogen production remains a significant challenge. Small-size bimetallic alloy nanoparticles have garnered considerable attention in the field of electrocatalysis due to their large exposure of effective active sites and optimal geometric/electronic effects. In this study, ultra-small bimetallic PtM (M=Ni, Co) alloy nanoparticles (approximately 1.7 nm) were synthesized on carbon supports through laser irradiation in liquids. This unique method leverages the effective absorption of pulse laser energy by carbon supports to generate high temperatures, enabling the reduction of metallic ions precursors by ethanol molecules and the subsequent formation of alloy nanoparticles. The resulting bimetallic PtNi alloy nanoparticles exhibited significantly improved catalytic performance in the hydrogen evolution reaction (HER).

Summary: In this study, we developed a hydrothermal sulfurization-acid assisted etching strategy to fabricate Mo doped NiS/Ni3S2 polymorph heterostructure with rich sulfur vacancies (Mo-NiS/Ni3S2-rich Sv). It was discovered that the S centers on the Ni3S2 side of the nickel sulfide polymorphs served as the H2-evolving sites, while the Ni sites on the Mo-NiS side facilitated the cleavage of the HO-H bond. The presence of rich Sv expedited the evolution of H* to molecular H2, leading to enhanced HER kinetics. The optimized Mo-NiS/Ni3S2-rich Sv electrocatalyst exhibited excellent HER activity and durability in alkaline solution. Understanding the synergy of polymorph heterostructure and element defect is crucial for the rational design of high-performance HER electrocatalysts.
