在壳聚糖改性的硅锆复合中间层上原位水热合成b轴取向silicalite-1分子筛膜
In-situ synthesis of b-oriented silicalite-1 membrane on chitosan-modified silica-zirconia intermediate layer
【Abstract】 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.
