有spheres-within-a-sphere的合并Cu的订的六角形的mesoporous硅酸盐(Cu-MCM-41)凹陷结构作为合作模板用thermoreversible聚合物hydrogelmethylcellulose(MC)和cationic表面活化剂被综合了,它被扫描电子显微图(SEM)描绘了,X光检查衍射(XRD),传播电子显微图(TEM),并且N2吸附解吸附作用等温线。获得的结果显示合并Cu的MCM-41材料的形态学是“spheres-within-a-sphere”空组织,它很类似于的蜂窝状。在有H2O2的苯hydroxylation,空范围比Cu-MCM-41的粒子显示出许多更高催化的活动。
