AbstractMoS2 has been proven to be an environmental-friendly and economic photocatalyst for clean energy generation. However, the energy conversion efficiency still needs to be more enhanced for practical application due to the limited number of active sites on the surface and the high recombination rate of electron-hole pairs. Herein, P-doping was utilized to increase the active sites, and the heterojunction was constructed with WO3 to improve the charge separation rate. Our results show that the heterojunction P-MoS2@WO3 photocatalyst has a stable and durable photocatalytic activity in water splitting, which shows H-2 evolution rate of 73.8 mu mol h(-1) g(-1). This good photocatalytic performance of P-MoS2@WO3 is attributed to increased active sites at the thermodynamically stable basal (002) plane of MoS2 by the P-doping and the enhanced charge separation rate by the heterojunction with a direct Z-scheme mode. This study offers an efficient way to increase the active sites and separate charge carriers in MoS2-based photocatalysts for H-2 generation. (C) 2021 Elsevier B.V. All rights reserved.
