Abstract:

With the increasing energy shortage and environmental problems, the search for clean and renewable energy sources to replace fossil fuels is one of the most urgent tasks facing scientists in this century. In order to achieve our "carbon neutrality" strategic goal, the conversion of carbon dioxide(CO2) into clean fuels and chemicals using solar energy is one of the ways to achieve the sustainable development of our society. The catalyst is the core component of CO2 photoreduction technology, which can adsorb gaseous CO2 molecules and reduce them to small energy molecules such as carbon monoxide(CO), formic acid(HCOOH), methanol(CH3OH) and methane(CH4) under visible light irradiation. Currently, promising progress has been made in the development of novel CO2 reduction photocatalytic systems. This review summarizes the recent progress of homogeneous and heterogeneous earth-abundant metalloporphyrin-based catalysts for photocatalytic CO2 reduction, and introduces the reaction mechanism of CO2 photoreduction to CO or CH4 by homogeneous metalporphyrin catalysts, respectively, and also discusses the important applications of metalloporphyrin-based porous organic polymers with porphyrin organometallic frameworks for photocatalytic CO2 reduction. Finally, the prospect of visible-light-driven metalloporphyrin complex-catalyzed CO2 reduction is presented.
