Abstract
The photocatalytic conversion of CO2 into sustainable, green fuels and value-added chemicals is believed to be an appealing method to overcome both the energy crisis and environmental problems. Numerous efforts have been dedicated to enhance the CO2 conversion efficiency and selectivity through developing photocatalysts and CO2 reduction systems in recent years. This review gives an overview of the latest progress in photocatalysts for visible-light photocatalytic CO2 conversion and recent research advances of heterogeneous photocatalytic CO2 conversion systems. Furthermore, The roles of cocatalyst and heterojunctions to increase the efficiency of charge transfer, separation and visible light excitation are discussed. Finally, the challenges and perspectives for visible-light-driven photocatalytic conversion of CO2 are proposed.
