摘　　要：膜与膜反应器是实现物质高效分离、反应/分离耦合的重要技术手段,在缓解能源、环境和资源所面临的重大问题方面发挥着日益重要的作用.本文根据膜孔大小和传质分离机理将膜分为大孔膜、微孔膜和致密膜三类,评述了不同种类分离膜的最新研究进展,探讨了进一步发展所面临的瓶颈和可能取得突破的方向,并对近年来以这三类膜为"芯片"的膜反应器在化学工程领域取得的研究进展进行了重点介绍,最后指出膜与膜反应器未来发展应重点关注的领域.Membranes and membrane reactors are providing approaches to realize high-efficient separation and reaction/separation coupling, thus making increasingly important contributions to address the global issues of energy shortage, environmental pollution, and resources depletion. In this work, we categorize membranes into three main groups, macroporous, microporous, and nonporous membranes, according to their mass transfer and separation mechanisms. We review the latest significant achievements of these membranes, and discuss the bottlenecks and potential breakthoughs of their future development. Furthermore, we make a more detailed survey on the recent progresses in membrane reactors, and conclude this paper with a perspective on the research areas requiring focused attentions of membranes and membrane reactors.
