摘要
考察了采用溶胶-凝胶化学合成法制备微-介复合材料的制备条件对复合材料制备的影响。采用XRD、SEM以及N2物理吸附-脱附等表征手段对复合材料进行了表征。结果表明,在加入异丙醇的情况下,采用超声震荡和机械搅拌的混合方式均可以很好地制备壳层均匀的微-介孔复合材料;而在没有异丙醇时,采用两种混合方式制备的微-介孔复合材料的表面比较粗糙,而且壳层结构参数也不相同。在优化了实验室制备条件的基础上,对微-介孔复合材料进行了工业放大。结果表明,采用优化的制备条件制备的微-介孔复合材料完全满足指标要求,并且制备过程重复性好。
The preparation of composite materials with sol-gel chemical synthesis method is investigated. The obtained products are characterized by XRD、SEM and N2adsorption-desorption techniques. The result indicates that micro- and mesoporous composite materials can be prepared using ultrasonic oscillations and mechanical stirring mixing method in presence of isopropyl alcohol. However,in the absence of isopropyl alcohol,different mix styles result in distinguishing shell structure. On the base of optimized conditions,micro- and mesoporous composite materials are prepared in industrial scale. The result suggests that the product can meet the requirement of index,and the synthesis process has good repeatability.
