The exploration of proficient and stable H2 producing photocatalysts, specifically materials without noble metals, is highly anticipated, to initiate solar fuel generation for practical applications. Herein, novel CdS-Bi2MoO6 core–shell heterostructures (CdS-BMO CSHs) are prepared by a two-step solvothermal method, in which Bi2MoO6 nanosheets are grown on the surface of CdS nanorods. The resultant CdS-BMO CSHs display efficient charge separation and a low electron–hole recombination rate, promising excellent interfacial charge transfer properties. Meanwhile, the enhanced specific surface area and pore structure impart CdS-BMO CSHs with abundant active sites for the H2 evolution reaction. As a result, a heterojunction of CdS-BMO CSHs shows remarkable improvement in the photocatalytic H2 evolution reaction under visible light irradiation. The H2 evolution rate of optimized CdS-BMO CSHs is six times that of pristine CdS and ten times that of Bi2MoO6 nanosheets. This work could contribute to the further development of novel and highly efficient photocatalysts for the H2 evolution reaction.
