Facile Synthesis of Zn0.5Cd0.5S Ultrathin Nanorods on Reduced Graphene Oxide for Enhanced Photocatalytic Hydrogen Evolution under Visible Light

Abstract A new contact model between Zn x Cd 1− x S nanorods and reduced graphene oxide (RGO) was obtained by rational formation of ultrathin Zn 0.5 Cd 0.5 S (ZCS) nanorods on RGO through a facile oleylamine–DMSO mediated synthesis approach. The 1 D/2 D model of ZCS/RGO provides a strong contact line‐to‐line interface, which is not only conducive for the fast collection and transfer of photogenerated electrons but also stabilizes the ultrathin nanorod structure of ZCS. The photocatalytic test results indicated that the ZCS/RGO nanocomposites exhibit significantly enhanced photocatalytic H 2 evolution rate and cycling stability under visible light compared with free ZCS and the physical mixture of ZCS and RGO.
