Research Progress of Photothermal Reduction of CO2 Catalyzed by Metal Catalysts

Excessive emissions of CO2 lead to an increasingly serious environmental impact of the greenhouse effect. The reduction of CO2 into high value-added chemicals through electrocatalysis, photocatalysis, thermocatalysis, photothermal catalysis or photocatalysis is one of the effective ways to address CO2 emissions. Among them, the photothermal catalytic conversion of CO2 is one of the main research areas at present. This paper summarises the classification of photothermal catalysis: thermal-assisted photocatalysis, photo-assisted thermocatalysis, photo-driven thermocatalysis and photo-thermal co-catalysis, and details the corresponding catalytic mechanisms, summarises the latest research progress on metal catalysts for photothermal catalytic CO2 reduction, and finally presents the challenges and prospects for photothermal catalysis.
