Semiconductor-based CO2 photoreduction for generating chemical energy has recently attracted special attention owing to its tremendous potential for solving increasingly grim energy crises and environmental concerns. Among them, Cadmium sulfide (CdS)-based nanomaterials have attracted enormous attention on account of the relatively narrow band gap for harvesting visible-light and well-suited band position for CO2 photoreduction. Herein, the comprehensive review focus on the application and progress in CO2 photoreduction over CdS-based photocatalysts. In this review, we begin with a detailed discussion of CdS materials in CO2 photoreduction, including fundamental of CO2 photoreduction as well as products selectivity. In particular, we will highlight the modification of CdS materials for efficient CO2 photoreduction. And the utilization of density functional theory (DFT) in the study of CO2 photoreduction over CdS-based photocatalysts is emphasized. Moreover, the remaining challenges to investigate and optimize the catalyzing ability of CdS-based catalysts are stated to indicate possible future development of CdS.
