| Abstract: | Mesoporous silica (meso-SiO2) was coated on the micro/nanomaterials with hierarchical structure such as flowerlike Fe2O3, flowerlike MgO, SnO2 nanospheres, Co3O4 nanosheets and nanowires from a simple solution method. The structure of the nanomaterials and the silica coating before and after stirring in solution were characterizated by SEM and TEM. The results show that meso-SiO2 coating was an ideal method to enhance the structural stability of fragile nanomaterials. The catalysis stability of flowerlike MgO was also enhanced by the meso-SiO2 coating. |
