M-xenes and mxene based nanocomposites: a new generation potential materials for removal of organic contaminants from water

Water pollution due to organic compounds has emerged as a global concern. Among various methods for wastewater treatment like advanced oxidation process, photodegradation, reverse osmosis, etc., adsorption is an economical and effective method. Different research scientists have focused on developing low-cost materials for the adsorption of organic pollutants from aqueous streams. The Discovery of M-xenes has led to a new and interesting vein of research. This article summarises M-xenes and M-xenes based nanocomposites for wastewater treatment. Adsorption kinetics and mechanism is also discussed in this paper. The adsorption is due to chemical attractions between pollutants and functional groups on the surface of M-xenes. Surface modified M-xenes have the potential to be excellent adsorbent materials for water remediation. Various factors affecting the adsorption capacity of M-xenes are discussed. Lastly, the future prospects for developing M-xenes as efficient, low-cost and non-toxic materials for water remediation are also addressed.
