Semiconductors are the low cost and recyclable photocatalysts for visible-light photoredox catalysis, which is one of the prospective ways to convert solar energy to chemical energy in organic synthesis. This study reports a new MoS₂/ZnO composite for the aerobic oxidation of benzyl halides under visible light. Despite the limited intrinsic activity of the ZnO alone, we found that the introduction of a small amount of MoS₂ nanosheets (4 wt %) could significantly improve the catalytic performances of the ZnO in visible-light photoredox catalysis.
