Converting CO into renewable solar fuel using photocatalysts is one of the most ideal solutions for environmental challenges and energy crises. Here, the solid-solid Z-scheme ZnCdS/Au@g-CN (ZCS/Au@CN) heterojunction showed improved photocatalytic reduction of CO due to the enhanced visible light consumption, fast dissolution of photogenerated electron-hole pairs, quick interfacial transfer process of electrons, and enlarged surface area. Under visible-light irradiation, methanol (CHOH) was produced at a rate of 1.31 μmol h g over ZCS/Au@CN, roughly 43.6 and 32.7 folds higher than those observed over pure ZCS and CN samples. The analytical characterization results verified the role of AuNPs as an electron mediator, which improved the rapid extraction of photoinduced electrons and enhanced the reduction ability of CO. This work not only demonstrates a facile photodeposition assisted hydrothermal method for fabrication of ZnCdS/Au@CN heterojunction composite photocatalysts but also demonstrates the possibility of utilizing ternary composites for enhanced photocatalytic reduction of CO.
