摘要

A novel method was developed for the preparation of titanium silicalite-1 (TS-1) zeolite membrane with low cost through tetrapropylammonium bromide (TPABr)/weak organic base synthesis system, in which TS-1 crystals grew on an unseeded support from a synthesis gel containing seeds. This membrane reactor showed relatively high catalytic activity for the oxidation of 2-propanol.
