Abstract
Two–dimensional (2D) nanosheet materials with unique atomic thickness have become emerging building blocks for separation membranes. Recently, the separation membranes utilizing a variety of 2D nanosheet materials have been developed, and their fabrication methods, membrane performances as well as permeation mechanisms have been demonstrated. In this review, recent developments of 2D nanosheet membranes for liquid separation with three basic forms: nanoporous membrane, layered membrane and hybrid membrane are summarized. The promising research areas are highlighted and future directions are briefly discussed.
