The reduction of CO2 to C2+ products using photoelectrochemistry (PEC) is significant and highly challenging. However, systematic summaries on PEC CO2 conversion into C2+ products are lacking. Therefore, this paper systematically reviews the current research status of the PEC CO2 conversion for the preparation of C2+ products, including the pathways of C2+ products, the usage of catalysts and reactors, and methods for improving C2+ product selectivity. Besides, the deficiencies in current research are analyzed, and future developments are discussed.
