宁波材料所在气体吸附分离材料研究中取得新进展金属有机框架材料(MOF)是一类新型的有机-无机杂化多孔晶体材料,具有高比表面积、孔容、孔隙率和孔径可调等特性,在氢气、甲烷和二氧化碳等气体的吸附分离领域受到了广泛关注。近年来很多MOF或MOF/聚合物复合气体分离膜不断被设计与开发出来,然而这些膜材料很难同时兼有气体的高渗透性和高选择性,而且以氧化铝陶瓷管为载体制备的MOF基分离膜很容易产生缺陷,
Recent advances in the study of gas adsorptive separation materials where Ningbo materials are located Metal-organic framework material (MOF) is a new type of organic-inorganic hybrid porous crystalline material with high specific surface area, pore volume, porosity and adjustable pore size. In the hydrogen, methane and carbon dioxide gas adsorption separation has received widespread attention. In recent years, many MOF or MOF / polymer composite gas separation membranes are continually being designed and developed. However, these membrane materials are difficult to combine gas permeation and high selectivity. Moreover, MOF with alumina ceramic tubes as carrier Base separation membrane is prone to defects,
