摘　　要：以十六烷基三甲基溴化铵为模板剂,偏硅酸钠为硅源,硝酸钇为钇源,用水热法合成了YOx-MCM-41介孔分子筛,经X射线粉末衍射法,FT-IR,热重分析,紫外漫反射法及N2吸附-脱附法表征。结果表明,该分子筛具有热稳定性好、比表面积大、孔道均一等典型的MCM-41介孔分子筛的特征。The mesoporous molecular sieve YOx-MCM-41 was synthesized by hydrothermal synthesis method with cetyltrimethy lammonium bromide as a template, yttrium nitrate as a yttrium source and sodium metasilicate as a silicon source. The YOx-MCM-41 was characterized by XRD, FT-IR, TG, DRS and N2 adsorption-desorption method. The results showed that the YOx-MCM-41 has an excellent thermal stability, a high BET surface area and a uniform pore size distribution, which coincides with MCM-41.
