Thermal processing of zeolite seed layers for the fabrication of compact oriented MFI zeolite films†
Abstract
A method of thermal processing was demonstrated to treat zeolite seeded substrates prior to secondary growth. Due to the formation of a strong covalent linkage between the seed layer and the substrate during heat treatment, a compact and uniform b-oriented MFI zeolite film was obtained after secondary growth. The applicability of this method is validated by employing various film substrates.
