COF

COF (Covalent Organic Framework) is an emerging class of crystalline ceramic materials synthesized through strong covalent bonds between organic building blocks, creating highly ordered porous structures. These materials are primarily under development for advanced filtration, gas storage, and separation applications where their tunable porosity and low density offer advantages over conventional zeolites and activated carbons. COFs are of particular interest in research and early-stage industrial applications for hydrogen storage, carbon capture, and molecular sieving due to their designable architecture, though they remain largely experimental compared to more established ceramic alternatives.
