MXENES FOR ENVIROMENTAL APPLICATIONS

Abstract

The development of new methods for obtaining clean water is one of the most important global problems of mankind. It is important to purify water from harmful impurities that can adversely affect human health and the environment. Natural renewable energy sources, such as solar radiation, can be perfectly used for cleaning, distilling and desalination of seawater. The analysis of the study showed that MXene with unique and customizable properties provide new strategies for effective water purification and desalination. Experimental results indicate that representatives of the two-dimensional materials family (Mxene) have demonstrated improved light absorption and water evaporation characteristics. Thus, MXenes demonstrate a huge potential in the production of solar energy in the form of steam to solve the problem of shortage of drinking water. And also, according to the results of research, MXene showed a high degree of adsorption of heavy metal ions, such as Pb (II), Cr (VI), Hg (II) and U (VI). The large surface area, abundance of active sites, good dispersibility and reducibility, and the fact that many cations can be spontaneously inserted between the layers of two-dimensional MXenes make them promising candidates for water purification from toxic oxidants associated with heavy metal ions, radionuclides, and organic dyes.
