As a promising solution to global warming and growing energy demand, photocatalytic CO₂ conversion to useful fuels is widely studied to enhance the activity and selectivity of the CO₂ photoreduction reactions. In this review, an overview of fundamental aspects of the CO₂ reduction photocatalysts is provided. The recent development of the photocatalyst is also discussed, focusing on the mechanisms of light harvesting and charge transfer. Besides, this review sets its sight on inspiring new ideas toward a practical CO₂ conversion technology.
