摘要
The b-oriented silicalite-1 membrane on the substrate α-Al2O3 pre-coated with a silica-zirconia intermediate layer was synthesized by using in-situ crystallization. The influence of chemical properties of the substrate surface on crystal growth and orientation was investigated. The result indicated that the surface modification by pre-coating a thin film of chitosan was conducive to the formation of b-oriented silicalite-1 membrane with good quality.
