摘要
实验以Ce(NO3)3.6H2O和Cu(acac)2为原料溶于乙醇制备前驱体溶液,采用浸渍法在MCM-41有序介孔二氧化硅微球中负载Ce/Cu氧化物,最终得到负载氧化铈和氧化铜的MCM-41多孔复合微球。结果表明,Ce/Cu负载于微球的介孔中;随着浸渍液体积的增加,Ce/Cu负载量增大。
Ce（NO3）3 · 6H2O and Cu（acac）2 were dissolved in ethanol. Ceria and copper oxide were loaded on MCM-41 mesoporous silica microspheres by the impregnating method using the precursors solutions. The results show that Ce/Cu were mainly loaded inside the mesopors of porous micropsheres. The Ce/Cu loadings increase with the volume of the precursor solutions used.
