摘要：

In recent years, there have been many studies on photocatalytic water splitting, but there are still few high-efficiency photocatalysts for photocatalytic seawater splitting. In this study, a series of hollow Co sulphide-supported CdS catalyst (H-CoS/CdS) composite photocatalysts were prepared by loading CdS onto the surface of H-CoS, which can be used for efficient H-2 production in pure water and simulated seawater. The heterojunction H-CoS/CdS exhibited H-2 production of 572.4 mmol g(-1) (4 h) from simulated seawater, which is 97.7 and 2.96 times those of H-CoS and CdS, respectively. The h-CoS cocatalyst extended the light absorption range of CdS, improved the chemical stability, and significantly enhances the charge separation efficiency. This study provides guidance for the reasonable design of a photocatalytic seawater-based H-2 production catalyst with high efficiency and low cost. (c) 2022 Hydrogen Energy Publications LLC.
