Preparation of Three-Dimensionally Ordered Macroporous Metallic Oxide Materials by Colloidal Crystal Templating Method

Yucui Zhao

Abstract

Three-dimensionally ordered macroporous TiO2 and ZrO2 materials were successfully synthesized by gravitational sedimentation PS microspheres as colloidal crystal template and ethanol solutions of metal alkoxides as precursor.The interstices between template microspheres was filled with precursor solution which concentration was 50% by capillary force,and eventually PS template was removed by two-step calcinations.The SEM and TEM images indicated that the macroporus structures were arranged orderedly and periodically in a face-centered cubic(fcc) structure.The obtained samples can be looked as the inverse duplication of PS template,although there were some shrinkages.The results of XRD showed the cell wall of the macroporous samples consisted of anatase and monoclinic phase,respectively.
