Covalent organic frameworks for CO₂ adsorption: fundamentals, structural features and synthesis

In the last ten years, covalent organic frameworks (COFs) which are crystalline, polymers with greater porosity and surface area, have attracted much research interest. The COF materials are made by covalently bonding organic molecules in a pattern that repeats to create a permeable crystal that is perfect for the sorption and storage of gas. They are expedient in the adsorption of contaminants such as CO₂ due to their appealing qualities including durability, improved reactivity, permanent porosity, and increased surface area. This study is an effort to report topology patterns, pore design, Synthetic Reactions of COFs, different methods for the synthesis of COFs and their applications for CO₂ adsorption. This review further focused on the current literature on the adsorption of CO₂. Graphical Abstract: (Figure presented.)
