Abstract Graphene oxide (GO) membranes, as laminated and channel-rich architectures assembled by stacked GO nanosheets, have surpassed other two-dimensional (2D) nanomaterials and present preeminent structural specialization and potential applicability in a wide range of environmental applications. This review mainly surveys the latest GO-based macroscopic membranes, which feature distinct functionalized structures, interior fluid flows, and tunable physicochemical properties. The GO-based membranes are classified and presented in three typical forms: single-layered porous GO membranes, few-layered laminated GO membranes, and multi-layered composited GO membranes. More attention is paid to target-oriented preparation strategies for the assembly of GO building blocks, involving multiple interactions and technical advantages, and to the resulting membrane characteristics. The overview also explores the serviceability of these GO-based membranes for full-scale use in environmental practices in gas, water, and biological treatments to pave the way for the promising development and realization of their prospects.

氧化石墨烯膜：功能结构、制备和环境应用

摘要 氧化石墨烯 (GO) 膜是由堆叠的 GO 纳米片组装而成的层状和通道丰富的结构，已超越其他二维 (2D) 纳米材料，并在广泛的环境应用中表现出卓越的结构专业化和潜在适用性。这篇综述主要调查了最新的基于 GO 的宏观膜，其具有不同的功能化结构、内部流体流动和可调的物理化学性质。基于GO的膜分为三种典型形式：单层多孔GO膜、少层层压GO膜和多层复合GO膜。GO积木组装更注重面向目标的制备策略，涉及多重交互和技术优势，以及由此产生的膜特性。概述还探讨了这些基于 GO 的膜在气体、水和生物处理的环境实践中全面使用的适用性，为有前景的发展和实现其前景铺平了道路。
