Abstract

Cocatalyst can greatly facilitate the charge separation efficiency and decrease the activation barrier of a specific reaction, thus contributing the improved photocatalytic performance. Herein, PdS/CdS/MoS₂ was synthesized via a facile microwave-assisted approach. Owing to the coexistence of PdS and MoS₂, respectively serving as oxidation and reduction cocatalyst, PdS/CdS/MoS₂ displayed enhanced photocatalytic performance in both hydrogen production (6610 μmol·g⁻¹·h⁻¹) and benzylamine oxidation (87% conversion) in comparison with the individual and binary composite counterparts. The improved photocatalytic activity was mainly attributed to the high charge separation efficiency and lowed activation barrier. Furthermore, the introduction of PdS can timely extract photogenerated holes from CdS, which effectively inhibits the photo-corrosion of CdS, endowing it with high stability. This work paves the way for developing efficient chalcogenide photocatalysts. © 2022 Elsevier B.V.
