Research progress of Metal–Organic Frameworks (MOFs) for CO2 Conversion in CCUS

With the widespread use of fossil energy, the environmental problems caused by CO2-based greenhouse gases are becoming more and more serious. The key to solving these problems lies in the reduction and reuse of CO2. Recent studies have shown that metal–organic framework (MOF) materials are widely used in CO2 catalytic reduction because of their porous structures, large specific surface areas, regular pore morphologies, and flexible tunability in terms of components and structure. This paper reviews recent research on several common MOF catalysts for the CO2 conversion process. The mechanism, research progress, and development prospects of MOFs for thermal catalytic reduction, photocatalytic reduction, and plasma catalytic reduction of CO2 in recent years are then discussed. Finally, the prospects and challenges of MOFs in CO2 conversion are proposed. The paper is instructive for the discovery of novel and efficient MOF catalysts.
