Abstract

Metal-organic frameworks (MOFs) have emerged as promising materials and have attracted researchers due to their unique chemical and physical properties—design flexibility, tuneable pore channels, a high surface-to-volume ratio that allow their distinct application in diverse research fields—gas storage, gas separation, catalysis, adsorption, drug delivery, ion exchange, sensing, etc. The rapidly growing CO2 in the atmosphere is a global concern due to the excessive use of fossil fuels in the current era. CO2 is the prime cause of global warming and should be ameliorated either through adsorption or conversion into value-added products to protect the environment and mankind. Nowadays, MOFs are exploited as a photocatalyst for applications of CO2 reduction. Since the use of semiconductors limits the use of visible light for photocatalytic reduction of CO2, MOFs are promising options. The current review describes recent development in the application of MOFs as host, composites, and their derivatives in photocatalytic reduction of CO2 to CO and different organic chemicals (HCOOH, CH3OH, CH4). Efficient charge separation and visible light absorption by incorporation of active sites for efficient photocatalysis have been discussed. The selection of material for high CO2 uptake and potential strategies for the rational design and development of high-performance catalysts are outlined. Major challenges and future perspectives have also been discussed at the last of the review.
