摘要
Water scarcity and pollution are one of most grand challenges facing humanity in the 21st century. Due to the low energy consumption and low cost, membrane technology is a green and efficient water treatment technology. Graphene oxide (GO) nanosheets with atomic thickness and excellent chemical stability have been recognized as an excellent two-dimensional (2D) membrane material, holding great promise in developing membranes for sustainable water treatment. In this paper, the development of GO membranes for water treatment is reviewed. Aiming to overcome two major challenges, low permeation flux and membrane fouling, of the membrane technology for water treatment, the mesoscale issues during the construction of nanochannels and surfaces of GO membranes are emphasized. In detail, the influence of the intercalator with different scales on the nanochannel structure and separation performance of the GO membranes is discussed. The antifouling strategies of GO membranes against foulants with different scales is analyzed. Finally, the brief summary and tentative perspectives of high permeation and antifouling graphene oxide membranes are presented. © 2022 Chemical Industry Press. All rights reserved.
