Abstract:
1. A fabrication of a zeolite composite film, comprising: mixing a composition of water, aluminum isopropoxide, TMAOH, and TEOS according to a set ratio to form a first mixture, and hydrolyzing the first mixture by stirring in room temperature, then heating to obtain a second mixture; taking an upper layer suspension obtained from a centrifugation of the second mixture, wherein the upper layer suspension comprises a plurality of zeolite crystals and a plurality of silicon colloids, and particle sizes of the zeolite crystals are less than 50 nm; preparing a mesoporous particle suspension, wherein the mesoporous particle suspension comprises a plurality of mesoporous particles, and each mesoporous particle comprises a plurality of pores and a plurality of templating agents inside the pores; applying a heat treatment to a substrate; mixing the upper layer suspension and the mesoporous particle suspension to form a mixture suspension, and vaporizing the mixture suspension to form a plurality of vaporized droplets; and depositing the vaporized droplets on the heated substrate to remove the templating agents in the mesoporous particles and to form a zeolite composite film, wherein the zeolite composite film comprises a plurality of macroporous, mesoporous and microporous structures.
