Abstract

We report that MoS2 nanosheets (MoS2 NSs) as a cocatalyst in situ coupled with MAPbI3 lead to a highly efficient composite photocatalyst for visible-light-driven photocatalytic H2 evolution. The most efficient MAPbI3/MoS2 NSs composite exhibits a high H2 evolution rate (206.1 μmol h−1) in MAPbI3-saturated HI solution, which is 121 times higher than that of pristine MAPbI3 (1.7 μmol h−1) and greatly superior to that of MAPbI3/Pt/C (68.5 μmol h−1), and the composite is very stable for H2 evolution in a 156 h reaction.
