An overview of catalytic conversion of CO2 into fuels and chemicals using metal organic frameworks.

[Display omitted] • MOFs in presence of co-catalyst TBABr are attractive for cycloaddition of CO 2 to epoxides. • Photocatalytic activity of MOFs is enhanced by implantation of atoms, semiconductors, photosensitizers etc. • The product selectivity depends on active metal nodes/clusters, ligands, visible-light absorption, conductivity, efficient charge separation etc. • The application of MOFs has been proven for efficient synthesis of formate, formic acid, alcohols, carbon monoxide, methane etc. Abundant CO 2 emissions from industries and the transportation sector cause an alarming threat to the planet due to overwhelming concerns over CO 2 induced climate change. To resolve this tremendous environmental pollution, the long-term solution for CO 2 mitigation exists in the conversion of CO 2 into value-added products through catalysis. Among several catalysts, metal organic frameworks (MOFs) are one of the remarkable candidates for CO 2 conversion into fuels and chemicals. The MOFs are molded with robust structures, high porosity, high potential of CO 2 adsorption, maximum atom utilization due to high dispersion and isolation of active sites of MOFs, tunability of the metal nodes, organic ligands, etc. MOFs have been implemented for several CO 2 conversion processes such as cycloaddition of CO 2 to epoxides, photocatalytic CO 2 reduction, electrocatalytic CO 2 reduction, hydrogenation, and others. These processes convert CO 2 into products like cyclic carbonates, alkyl formate, formic acid, ethanol, methanol, methane, CO, and others. This study strived to explain elaborately the formation of fuels and chemicals through different catalytic processes using MOFs. Detailed reaction conditions, catalyst chemistry, reaction mechanisms, and formation rates for alkyl formate, formic acid, methanol, ethanol, CO, and methane have been critically analyzed in present study.
