CoNi-layered double hydroxide derived CoS/NiS dodecahedron decorated with ReS Z-scheme heterojunction for efficient hydrogen evolution.

The high efficient utilization of light absorption and the effective separation of photogenerated carriers are critical factors in enhancing the performance of photocatalysts. In this study, CoNi-layered double hydroxide was synthesized using zeolitic imidazolate frameworks-67 as a template, followed by calcination to form CoS/NiS. Subsequently, ReS was deposited onto the surface of CoS/NiS, resulting in the ReS/CoS/NiS photocatalyst demonstrated notable hydrogen evolution activity under visible light, achieving a maximum hydrogen production rate of 40111.
