Abstract

The photocatalytic CO2 reduction to high-value chemicals has attracted significant global interests. Despite extensive research, the efficiencies of the reported photocatalysts are hindered by inadequate light absorption, limited photoelectron transfer rates, and other associated factors. In this study, we present a facile synthesis of a novel Cu&P@C3N4, catalyst, featuring Cu-Cu coordination and P doping. Compared to pristine C3N4, the carrier separation efficiency and light absorption capacity of Cu&P@C3N4 are both significantly enhanced. This catalyst exhibits a remarkable photocatalytic CO2 reduction activity, achieving a performance of 25.1 times greater than pristine C3N4, coupled with exceptional CH4 selectivity exceeding 96%. Our findings provide new insights into the design and synthesis of high-efficient and low-cost photocatalysts, paving the way for advancements in CO2 reduction reaction (CO2RR) technology and contributing to a more sustainable and environmentally friendly future.
