Abstract
Two–dimensional graphene–based nanosheets have attracted significant attention in a variety of fields owing to the distinct physical and chemical properties. The building block–like nanosheets have been manipulated and assembled as membranes showing intriguingly selective property for separations. Specifically, the nanometer and sub–nanometer scale confined space created by graphene materials exhibit distinct water transport behavior, which allows researchers to develop high performance water-selective membranes. Two main types of effective transport pathways have been created including graphene nanopores and nanochannels using different graphene materials and fabrication methods. In this review, the confined water transport in the nanopore and nanochannel is highlighted by discussing the recent advances in both theoretical and experimental perspectives.
