摘　　要：以硅酸钠、氯化铜等无机盐为原料,十六烷基三甲基溴化铵(CTAB)为模板剂,通过微波辐射方法合成不同铜含量的Cu-MCM-41介孔分子筛。分别采用X射线粉末衍射(XRD)、透射电子显微镜(TEM)和N2吸附-脱附等技术对产物的晶相、结构、形貌、比表面积和孔径分布进行表征。结果表明,通过微波辐射方法成功地合成出含有不同孔径的Cu-MCM-41介孔分子筛。随着原料配比中n(CuO)∶n(S iO2)(摩尔比)的增加,介孔分子筛的比表面积和孔体积变小,介孔有序性变差。Cu-MCM-41 mesoporous molecular sieves were synthesized by a novel microwave irradiation method with cetyltrimethyl ammonium bromide as a template, and inorganic salt sodium silicate and copper chloride as raw materials. sieves with different pore sizes can be successfully synthesized by microwave irradiation method. The specific surface area and pore volume of the synthesized Cu-MCM-41 mesoporous molecular sieves decrease, and the mesoporous ordering of the samples becomes poor with the increasing of the molar ratio of CuO to SiO2 in the feedstock.
