Covalent Organic Frameworks for Water Treatment. Issue 1 (10th November 2020) - Xia, Zijing
Abstract: Covalent organic frameworks (COFs) are an emerging type of porous crystalline material with highly ordered aperture size and tunable structures with designer properties. COFs have been proposed as promising materials for water treatment because of their notable intrinsic properties like excellent chemostability, high surface area, abundant functional sites, and uniform adjustable aperture size. This review focuses on fundamental COF design principles for water treatment (stability, aperture size, and surface functionalization) and the state‐of‐the‐art application of COFs in desalination, organic contaminant sorption, and ion capture. Additional potential promising applications of COFs for water treatment, including solar steam generation, photocatalysis for degradation of organic contaminants, and capacitive deionization are also presented along with an outlook toward future opportunities in the field. Abstract : With extremely ordered aperture size, high surface area, chemostability, and tunable structure and chemistry, covalent organic frameworks are emerging as promising materials for water treatment in applications, such as desalination, nanofiltration, organic contaminant sorption, ion capture, photothermal evaporation, and beyond.
