| 摘 要： | 在水热合成体系中添加自制晶种导向剂成功制备了纳米ZSM-5沸石，考察了晶种导向剂、晶化温度和合成体系硅铝物质的量比对合成纳米ZSM-5沸石的影响。制备的晶种导向剂是全硅的Silicalite-1沸石纳米颗粒、沸石初级或次级结构单元的SiO2以及模板剂TPAOH的混合胶体溶液，结果表明，在ZSM-5沸石制备体系中添加晶种导向剂可有效降低有机模板剂的使用量，缩短晶化时间，并能得到纳米尺寸的ZSM-5沸石,降低晶化温度和合成体系硅铝比有利于减小纳米ZSM-5沸石晶体尺寸。

| Abstract: | Nanosized ZSM-5 zeolite was prepared by hydrothermal method with addition of as prepared seeding director. Effects of seeding director, crystallization temperature and silica/alumina molar ratio were investigated. The as prepared seeding director was a mixed colloid solution of nanosized all silica Silicalite-1 zeolites, primary and secondary silica building units for zeolite and TPAOH templates. It was shown that adoption of seeding director in hydrothermal preparation of ZSM-5 zeolite lowered the template dosage, shorten the crystallization time and resulted in nanosized ZSM-5 zeolite. Lowering crystallization temperature and alumina/silica molar ratio favored smaller nanosized ZSM-5 zeolite. |
