Abstract
Using semiconductor photocatalysts to achieve CO 2 photoreduction presents a promising approach to solving the environmental and energy crises caused by CO 2 emissions. Plasmon–perovskite hybrid photocatalysts for CO 2 photoreduction are garnering increasing attention owing to the excellent photoelectric properties of perovskites and the unique localized surface plasmon resonance effect of plasmonic materials. This review summarizes the latest progress and performance of plasmon-enhanced perovskite photocatalysts for photocatalytic CO 2 reduction. Simultaneously, the most pivotal mechanisms and other various mechanisms of plasmonic nanoparticles in improving photocatalytic activity were distinguished and analyzed. Finally, a summary of the current challenges and future development directions of these promising plasmon-enhanced perovskite photocatalysts is proposed to advance the development of efficient and sustainable CO 2 photoreduction in the field of perovskite photocatalysts.
