中文摘要： 能源危机和环境污染是二十一世纪人类面临的重大难题，针对这两大难题，氢气由于其高能效、零污染及应用广泛等特点，形成了以氢气为基础的新型能源经济体。基于此，氢气气体的分离成为有效利用现有能源焦炉煤气和甲烷重整制氢过程中的关键技术。构筑新型高性能膜分离材料是发展高效、经济的氢气分离技术的核心。本项目拟以多孔金属有机骨架化合物（Metal-organic frameworks, MOFs）的设计和调控为切入点，以无机膜为载体，制备一系列新型的、结构可控的、用于气体分离的MOFs/无机复合膜材料，达到氢气气体分离的目的。并在研究过程中揭示该MOFs/无机复合膜材料的微观组成、微观形貌以及宏观性能三个层面的特点，为高性能分离材料的设计、制备以及实际应用奠定一定的理论基础，在性能优异的新型多孔材料的器件化应用方面做出有益的探索。

英文摘要： With the emergence of energy crisis and environmental pollution, Hydrogen based Emerging energy Economy was formed owing to high efficiency, zero pollution and widespread applications of hydrogen. Separation of hydrogen from the other compound becomes the key technology during the process of efficient use of the existing coke oven gas and preparation of hydrogen from methane reforming. Construction of new membrane material with high performance efficiency is the core of the development of an efficient and economic separation technology. With the aim of preparation of a series of new structure controllable MOFs/inorganic composite membrane with high gas separation efficiency, we focus on the design and regulation of porous coordination compound and also process optimization of MOFs/inorganic composite membrane. Analysis the relationship between micro morphology and composition and macro performance try to provide theoretical basis for the design, synthesis and also application of High-performance separation materials further make beneficial exploration for the applications of device application of novel porous material.
