Recent investigations and progress in environmental remediation by using covalent organic framework-based adsorption method: A review

Adsorption is considered to be the most effective method for removing environmental pollutants. Covalent organic frameworks (COFs, state-of-art 2D or 3D crystalline porous polymers linked by covalent bonds) have been widely used in environmental remediation due to the superior physicochemical properties such as huge specific surface area, high porosity, admirable physicochemical stability, fast charge-carrier mobility, tunable functionality....
