Abstract	We reported herein a facile and scalable preparation process for MoS2-decorated ZnxCd1−xS hybrid photocatalysts for hydrogen generation. ZnxCd1−xS nanopowder was first prepared from commercially available precursors employing a solution based process. MoS2 hydrogen evolution reaction catalyst was then loaded onto the ZnxCd1−xS nanopowder via a photo-assisted deposition process which employed mild conditions (room temperature, atmospheric pressure and visible light illumination). Thus, this process represents an important advantage in the large scale production of semiconductor/MoS2 hybrid photocatalysts in comparison to the conventional method relying on thermal decomposition of (NH4)2[MoS4] precursor at high temperature and under H2S pressure. The best Zn0.2Cd0.8S/MoS2 3% showed two hundred-and-ten times (210 times) faster hydrogen generation rate on visible light illumination compared with that obtained for un-treated Zn0.2Cd0.8S. That was the most impressive catalytic enhancement ever recorded for a semiconductor photocatalyst decorated with a noble metal free electrocatalyst.
