摘　　要：采用水热法制备了一系列纳米硅铝酸盐材料,考察了晶化时间、模板剂、硅源、铝源、稀土离子掺杂等对材料制备的影响.发现以TEAOH为模板剂,白炭黑为硅源,硫酸铝为铝源,铈离子掺杂制备的硅铝酸盐在苯甲醛与吲哚的Friedel-Crafts烷基化反应中的催化活性最好.通过XRD,BET和SEM表征了该材料的结构特性.A series of nano aluminosilicate materials have been successfully prepared with hydrothermal method in this paper.The effects of crystallization time,template,silicon source,aluminum source and rare earth ions modification on the hydrothermal preparation of aluminosilicate materials were investigated.It was found that the cerium ion doped aluminosilicate prepared using TEAOH as template,SiO2·nH2O as silicon source and Al2（SO4）3·18H2O as aluminum source showed the best catalytic performance in the Friedel-Crafts alkylation of benzaldehyde and indole.Moreover,XRD,BET and SEM were employed to characterize their structural properties.
