Abstract

Background: Overall water splitting based on particulate photocatalysts under visible light irradiation is a cost-effective technology for the conversion of solar energy into renewable energy (hydrogen and oxygen). Methods: Herein, the perylene diimide (PDI)/Zn_0.8Cd_0.2S composite photocatalyst is synthesized for application in visible light driven photocatalytic overall water splitting. Significant findings: The PDI/Zn_0.8Cd_0.2S composite with 10 wt% PDI loading exhibits superior H₂-evolution rate of 71.98 μmol·g⁻¹·h⁻¹ and O₂-evolution rate of 32.44 μmol·g⁻¹·h⁻¹, which in a perfect stoichiometric ratio close to 2:1. The PDI/Zn_0.8Cd_0.2S with remarkable enhanced photocatalytic activity have the advantages of high charge separation efficiency and strong redox capacity. This work provided a new approach for the design of new type composite photocatalysts with efficient photocatalytic overall water splitting.
