Recent Advances in Covalent Organic Framework (COF) for Selective Photocatalytic Reduction of CO2

Photocatalytic transformation of CO2 into clean fuels and chemicals is a promising solution to address both the energy dilemma and environmental issues. Recent years have seen several efforts to improve CO2 conversion effectiveness and selectivity by creating photocatalysts and reduction devices. An alternative to fossil fuels is urgently needed to address rising energy demand and pollution. Porous heterogeneous catalysts are gaining popularity for carbon capture, with recent breakthroughs in design and application for CO2 conversion. COFs are porous crystalline polymeric materials made up of organic module units held together by strong covalent connections. COFs have numerous applications, including adsorption and separation, detection, catalysis, optoelectronic components, energy storage, and mass transport, due to their low density, massive specific surface area, superior thermal stability, developed pore structure, long‐range sequence, from good crystallinity, and excellent tunability of monomer units. In this review, we have discussed the synthetic process, morphology and linkage of COFs. Further, in second part we have elaborated the types of activations for CO2 i.e., thermal, electrocatalytic and photocatalytic activation. And the last part deals with the application of COFs for conversion of CO2 to VAC
