Insights into the function of metallic 1T phase tungsten disulfide as cocatalyst decorated zinc indium sulfide for enhanced photocatalytic hydrogen production activity

Improving the separation efficiency of carriers is an important part of enhancing photocatalytic activity. Herein, we successfully decorated metallic 1T phase tungsten disulfide (1T-WS(2)) on the surface of zinc indium sulfide (ZnIn(2)S(4)) and investigated the synergistic effect of 1T-WS(2) on ZnIn(2)S(4). The characterization results show that 1T-WS(2) improves the light absorption capacity and utilization efficiency, increases the catalytic active site, improves the photogenerated …
