  • Using close-packed colloidal crystals-silica as the template,a novel 3D well-ordered and long-ranged periodic macroporous material MnO2 has been prepared by colloidal crystals template methods. The prepared product has been characterized by means of X-ray diffraction(XRD)and scanning electron micrography(SEM). The X-ray diffraction displays that the phase of MnO2 is tetragonal,and the scanning electron micrography shows that MnO2 replicates the structure of the started template and exhibits 3D long-range ordered honeycomb framework. The process of preparing the 3D order macroporous MnO2 was discussed. The effect of the infiltration times to the final morphology of MnO2 was studied and an abnormity existed in the shrinkage of the final outcome.

Abstract: Using close-packed colloidal crystals-silica as the template,a novel 3D well-ordered and long-ranged periodic macroporous material MnO2 has been prepared by colloidal crystals template methods. The prepared product has been characterized by means of X-ray diffraction(XRD)and scanning electron micrography(SEM). The X-ray diffraction displays that the phase of MnO2 is tetragonal,and the scanning electron micrography shows that MnO2 replicates the structure of the started template and exhibits 3D long-range ordered honeycomb framework. The process of preparing the 3D order macroporous MnO2 was discussed. The effect of the infiltration times to the final morphology of MnO2 was studied and an abnormity existed in the shrinkage of the final outcome.
