Metal-organic frameworks (MOF)-based sensors for detection of toxic gases: A review of current status and future prospects

An amine decorated MOF for direct capture of CO2 from ambient air

“…MOFs, with their large surface area, high stability, open channels, and permanent porosity, are promising candidates for efficient CO 2 collection, catalysis, optics, magnetism, sensing, drug delivery, etc. [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] Compared to other adsorbents or catalysts, MOFs have a higher CO 2 capture efficiency, which can be attributed to their ability to catalyse CO 2 conversion processes. [30][31][32] In view of this, metal-catalyzed cycloaddition of CO 2 and epoxides is a potential methodology for synthesizing cyclic carbonates.…”
