Abstract
The massive consumption of fossil energy leads to excessive emissions of CO 2, which has caused global warming. Solar-driven CO 2 conversion is a promising avenue that could solve the energy crisis and environmental pollution issues simultaneously. For photocatalytic CO 2 conversion reactions, several photocatalysts have been developed such as semiconductors and plasmonic metal-based catalysts. Among them, plasmonic metal-based catalysts have attracted extensive attention due to their strong light harvesting capacities and low electron–hole pair recombination rates, which are beneficial for photocatalytic CO 2 conversion. This review summarizes the progress of plasmonic metal-based catalysts in CO 2 reduction with H 2, CH 4, H 2 O, and organic chemicals and generalizes the mechanism of plasmonic metal-based catalysts in CO 2 conversion reactions.
