2D isoporous materials: From precursor molecular structures to post-processing methods

Abstract

The emerging of two-dimensional (2D) isoporous materials forwarded the applications of membrane materials in cutting-edge fields such as refined separation, atom uptake and single-molecule detection. The key to the design of these materials lies in the precise tailoring of the pore structures. This review presents the state-of-the-art advancements of 2D isoporous materials, highlights the construction of isoporous structures in 2D materials through the bottom-up and top-down synthesis strategies, and reviews various fabrication routes. It comprehensively summarizes the impact of interface selection, precursor design and post-processing on pore formation, pore geometry and edge structures. The feasibility of the material scale-up, current challenges and future development prospects are outlined.
