MXene: A two-dimensional material in selective water separation via pervaporation

MXene, well-identified as Ti3C2TX, belongs to the family of two-dimensional (2D) materials, which have been currently explored in various applications. Very recently, such materials have been pointed out as potential nanomaterials for advanced solute separations when introduced in membranes, such as ion separation, gas separation, nanofiltration, chiral molecular separation, and solvent separation. This latter separation, generally named Pervaporation (PV), is identified as a highly selective technology for water separations. To date, few pieces of research have been released but providing interesting insights into several solvent (including water) separations. Hence, this brief review aims to analyze and discuss the latest advances for utilizing MXenes for PV membranes. Particular emphasis has been devoted to the relevant outcomes in the field, along with the strategies followed by researchers to tailor membranes. Based on the current findings, the perspectives in the field are also stated. (C) 2021 The Author(s). Published by Elsevier B.V. on behalf of King Saud University.

Automated summary

MXene as a 2D material shows potential applications in membrane separations, especially in PV membranes. Limited studies indicate the potential of MXenes in solvent separations, but more in-depth research is needed.
