摘要

以生物形态多孔SiSiC陶瓷为载体，采用原位水热法在多孔陶瓷微孔道内壁形成了一层2～5μm厚的b轴取向生长的ZSM－5分子筛膜. 利用XRD、SEMEDX、BET分析对复合材料的相组成、微观结构和比表面积进行了表征，研究了水热晶化时间、载体预处理对原位合成分子筛膜的影响. 结果表明，随晶化时间从5h增加到15h，从不连续的单层膜演变到～5μm厚的b轴取向的连续致密多层膜，该膜层是由粒径在1μm左右的ZSM-5分子筛颗粒堆积交联而成. 载体表面Si-OH浓度越高，分子筛膜和载体的结合力越强，但是较难控制分子筛膜的定向生长. ZSM-5/SiSiC复合孔结构材料的微孔体积为0.015cm3/g,BET面积为42.8m2/g,而相应的分子筛负载量为8.6%.

Abstract

Oriented ZSM-5 zeolite membranes on the biomorphic porous SiSiC ceramics were successfully synthesized by in situ hydrothermal synthesis. The ZSM-5/ SiSiC composite materials were characterized by XRD, SEM-EDX and BET. The effects of synthesis time and surface pre-treatment of the beech-derived SiSiC monolith were systematically studied. It shows that a homogeneous coverage within the pores channel of SiSiC monolith by b-oriented ZSM-5 crystals with 1μm average size is formed after hydrothermal treatment at 150℃ for 15h. The structure composites exhibit a hierarchical pore structure with a BET specific surface area of 42.8m2/g and microporous volume of 0.015cm3/g. The weight percent of ZSM-5 in the final zeolite/SiSiC composites is about 8.6% after coating.
