Mesoporous silica membrane on polymeric hollow fibers

摘要

A gas separation device comprising a porous support structure comprising polymeric hollow fibers, and an inorganic mesoporous membrane disposed on the porous support structure is disclosed. The inorganic mesoporous membrane is uniform and free of defects. Further, the inorganic mesoporous membrane comprises a network of interconnected three-dimensional pores that interconnect with the porous support structure. The gas permeances of the inorganic mesoporous membrane is substantially higher than the gas permeances of the polymeric hollow fibers. A method of fabricating the gas separation device is also disclosed.
