A simple, reliable and reproducible approach for the fabrication of highly b-oriented ZSM-5 zeolite membranes on rough surface is presented. The approach consists of depositing a TiO2intermediate layer on the rough surface of substrate, followed by UV irradiation, and subsequently in situ crystallization on the TiO2modified rough surface. The TiO2interlayer combined UV irradiation provides a smooth and high Ti–OH density surface for the growth of b-oriented ZSM-5 crystals. By comparing the morphology of zeolite membranes on Al2O3, SiO2, ZrO2, and TiO2, the impacts of smoothness, dispersion force between the zeolite crystal phase and substrate, and density of surface hydroxy on the formation of a highly b-oriented and continuous ZSM-5 membrane have been investigated. A smooth surface rich in Ti-OH was helpful for the continuous and uniform spread of the synthesis solution on the support, resulting in the oriented nucleation and accelerated growth of zeolite crystals, which formed the highly b-oriented and covered ZSM-5 membrane.
