Metal-organic precursor-derived novel ceramic based membranes have successfully synthesized. Microporous amorphous silica-based membranes having hydrogen affinity as well as conventional molecular sieve-like properties showed enhanced hydrogen permeance at and above 373 K. Organic/inorganic hybrid membranes composed of organoamino group-functionalized amorphous silica have been synthesized from silicon-based polymers. The facilitated transport of carbon dioxide was achieved by the organoamino groups as designed. For developing an efficient porous support for the ceramic membrane, macroporous alumina-based materials have been also designed and synthesized using alominosilicate polymers or alumina platelets.

金属有机前体衍生的新型陶瓷基膜已成功合成。具有氢亲和力以及传统分子筛性质的微孔无定形二氧化硅基膜在373 K及以上显示出增强的氢渗透性。由有机氨基官能化的无定形二氧化硅组成的有机/无机杂化膜已经由硅基聚合物合成。通过设计的有机氨基实现了二氧化碳的促进运输。为了开发陶瓷膜的有效多孔载体，还使用硅铝酸盐聚合物或氧化铝片晶设计和合成了大孔氧化铝基材料。
