Recent advances in the photocatalytic CO2 reduction over semiconductors

Abstract

This perspective gives an overview of recent developments in heterogeneous photocatalytic CO₂ reduction for C1/C2 fuels production over semiconductors, which has been known for several decades as a potential feasible means to store intermittent solar energy and to recycle CO₂. In recent years, significant efforts have been made in order to further improve the photoactivity and the selectivity through developing novel photocatalysts and its CO₂ photoreduction reaction systems, which would be of great interest in the field of solar conversion and CO₂ resource utilization.
