Synthetic membranes have been used in various processes, from water treatment, gas purification to energy conversion. The conventional membrane processes, including microfiltration, ultrafiltration, and reverse osmosis, have been commercialized and widely used in food, chemical, and medical industries. However, it remains challenging to realize the precise separation of the molecules/ions with subnanometer sizes, such as saline water, organic solvent solution, and gas mixtures. As we know, there is a general trade-off between permeability and selectivity for polymeric membranes. Although inorganic membranes could achieve both high permeability and selectivity, the high cost of membrane fabrication restricts their development. The key lies in the design and fabrication of high-performance (high permeability, selectivity, and stability) membranes for efficient molecular separation. Two-dimensional (2D) materials (e.g. nanosheets of graphene family materials, zeolites, metal–organic frameworks, or layered double hydroxides) have become excellent nanobuilding blocks to develop next-generation separation membranes featuring unique nanopores and/or nanochannels. Recently, 2D materials-based membranes have been appearing as a very hot topic both in theoretical and experimental studies and have attracted a huge surge of interest. Important new results demonstrated that the fascinating 2D-material membranes showed extraordinary permeation properties, opening the door to ultrafast and highly selective membranes for water purification, desalination, gas separation, and bioseparation. Up to now, books lacked an instructive view on the important contemporary topic “2D materials membranes.” There is an urgent need for a book that brings alive the new results, and current significances and challenges concerning 2D-material membranes. In this book, we aim to give comprehensive information on design, fabrication, and application of 2D-material membranes that are used for molecular separation.
