Graphene-based nanomaterials are versatile functional materials with extraordinary properties. Graphene-containing membranes (GCMs) are advanced separation devices constructed from or modified by graphene and its derivatives; these membranes not only present attractive functions and performance but also generate less residual nanomaterials afterwards, thus lowering impacts to the environment compared to those caused by directly using graphene-based nanomaterials. Since GCMs demonstrate significant sustainability in various applications, they have attracted tremendous attention from both academia and industry. To summarize the state-of-the-art works and guide the future development of GCMs, a full survey of the theoretical and experimental approaches using graphene-based nanomaterials to construct new membranes and modify existing membranes is provided in this review. GCMs are divided into monolayer porous graphene membranes (SGMs), multilayer pristine graphene-containing membranes (MGMs), multilayer composite graphene-containing membranes (CGMs), and conventional membranes modified with graphene-based materials (PGMs). Subsequently, the applications of GCMs in isotope separation, gas separation, desalination, ion separation, nanofiltration, ultrafiltration, and pervaporation are summarized. Multifunctional GCMs with conductive, antifouling, adsorptive, and photoactive properties are also illustrated. The environmental impacts of graphene-based nanomaterials and the safe-by-design concept for GCMs are subsequently discussed. The mechanisms behind GCM construction and GCM performance/function are highlighted. In addition to the advantages of graphene-containing membranes over conventional membranes, the challenges during GCM fabrication and their limitations are analysed to envision the development of next-generation graphene-containing membranes.

由石墨烯基纳米材料制备的膜在可持续应用中的应用：综述
石墨烯基纳米材料是具有非凡性能的多功能功能材料。含石墨烯的膜（GCM）是由石墨烯及其衍生物构造或由石墨烯及其衍生物改性的高级分离装置。这些膜不仅具有吸引人的功能和性能，而且之后产生的残留纳米材料更少，因此与直接使用基于石墨烯的纳米材料相比，对环境的影响更低。由于GCM在各种应用中显示出显着的可持续性，因此引起了学术界和工业界的极大关注。总结最新的工作并指导GCM的未来发展，这篇综述提供了使用石墨烯基纳米材料构造新膜并修饰现有膜的理论和实验方法的全面调查。GCM分为单层多孔石墨烯膜（SGM），多层原始含石墨烯的膜（MGM），多层复合含石墨烯的膜（CGM）和用石墨烯基材料改性的常规膜（PGM）。随后，总结了GCM在同位素分离，气体分离，脱盐，离子分离，纳滤，超滤和全蒸发中的应用。还展示了具有导电，防污，吸附和光敏性能的多功能GCM。随后讨论了石墨烯基纳米材料对环境的影响以及GCM的安全设计概念。重点介绍了GCM构建和GCM性能/功能背后的机制。除了含石墨烯的膜优于传统膜的优点外，还分析了GCM制造过程中的挑战及其局限性，以期开发下一代含石墨烯的膜。
