Construction of NiP x /MoS 2 /NiS/CdS composite to promote photocatalytic H 2 production from glucose solution

Constructing multi‐component photocatalyst is an efficient method to achieve high photocatalytic efficiency. In this work, CdS nanorods modified with NiS nanoparticles are first prepared to improve the photocatalytic performance, as no H 2 generates on single NiS or CdS catalyst from glucose solution. MoS 2 and NiP x , as the cocatalysts for H 2 production, are loaded on the surface of NiS/CdS composite. With step‐by‐step solvothermal synthesis, four components (CdS, NiS, Mo 2 S, and NiP x ) are fully combined in the NiP x /MoS 2 /NiS/CdS nanorods, generating many intimate contact interfaces. Moreover the optimized NiP x /MoS 2 /NiS/CdS performs a significantly increased photocatalytic activity, with H 2 production rate at 297 µmol h –1 g –1 . The synergistic effects of heterostructure (NiS/CdS) and cocatalysts (MoS 2 and NiP x ) are the main reasons in enhancing photocatalytic performance, which facilitate the separation of charge carriers and prolong their lifetimes. This work provides an effective strategy to design photocatalysts with multiple components and fast charge separation for highly efficient H 2 production.
