Rapid synthesis of zeolite film coating on stainless steel
The rapid synthesis of zeolite thin film coating on metal surface was demonstrated for LTA, FAU, EMT, SOD, CAN and JBW on stainless steel. The direct heating of LTA-seeded stainless steel was achieved in a specially made synthesis reactor enabling rapid heat transfer that promote zeolite deposition and growth. Microns thick zeolite film can be grown on the stainless steel with an acceptable degree of intercrystalline defects in a relatively short crystallization time (i.e., 45 min). The type of zeolite deposited can be controlled from the starting composition of the synthesis mixture, the ageing time and substrate temperature enabling the preparation of both pure and mixed phase zeolites.
