Dual modified MoS2/SnS2 photocatalyst with Z-scheme heterojunction and vacancies defects to achieve a superior performance in Cr (VI) reduction and dyes degradation

Efficient and sustainable wastewater treatment requires highly active and controllable photocatalysts. Defect engineering and heterojunction are two promising approaches in enhancing the activity of photocatalysts, but the synergy effect between them has rarely been studied. In this paper, we announced an intelligible hydrothermal method to craft a direct Z-scheme heterostructure photocatalyst by growing MoS2 on the surface of vacancy-rich SnS2....
