RESUMO
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 CoS2/NiS2. Subsequently, ReS2 was deposited onto the surface of CoS2/NiS2, resulting in the ReS2/CoS2/NiS2 photocatalyst demonstrated notable hydrogen evolution activity under visible light, achieving a maximum hydrogen production rate of 40111.8 µmol/g. The construction of the Z-scheme heterojunction was found to facilitate the transfer and separation of photogenerated carriers while extending the lifetime of photogenerated electrons, thereby contributing to the enhancement of photocatalytic activity. This study provides a new approach for the development of sulfide heterojunctions aimed at improving photocatalytic hydrogen production efficiency.
