摘要
发展高效、绿色且节能的物质分离与纯化技术具有重要意义,气体分离更是在工业、能源、医疗及科技等领域有着广泛的应用.传统的聚合物膜在实现高效气体分离方面还面临许多挑战,新型分离膜材料的开发是当前研究热点和难点.金属-有机框架(Metal-OrganicFrameworks,MOFs)材料作为一种新兴多孔配位聚合物,由于其具有独特可设计的拓扑结构以及可调节的功能而受到科学家们的广泛关注.为了克服粉体或块体MOFs很难被高效用于气体分离的难题,开发可用于分离的MOFs膜材料是一项具有重要意义且具有挑战性的任务.HKUST-1作为一种代表性的MOFs材料,由于其结构稳定且原料经济并具有多级孔径的结构,常被用作制备成膜材料用于气体分离的研究和实际应用.总结了近十年HKUST-1膜的制备方法及其气体分离性能的研究进展,并对这个方向的研究提出了自己的看法和展望.
The development of high-efficiency,green and energy-saving material separation and purification technology is of great significance,and gas separation has a wide range of applications in the fields of industry,energy,medical treatment and technology.Since traditional polymer membranes still face many challenges in achieving high-efficient gas separation,the development of new separation membrane materials has become the current hotspot and difficult issue.As an emerging porous coordination polymer,metal-organic frameworks(MOFs)materials have attracted great attention due to their unique,designable topological structures and tunable functionalities.In order to overcome the problem that bulk or powder MOFs are difficult to be used for gas separation efficiently,it is of great significance and a challenging task to develop MOFs membranes for separation.As a representative MOF material,MOF HKUST-1 is widely used to prepare membranes for gas separation due to its advantages of high stability,economic raw material and hierarchical pore structure.The preparation methods and gas separation performances of the HKUST-1 membrane in the past ten years are summarized,and some viewpoints and the research prospect on this research area are described.
