Ordered macroporous materials have been prepared by colloidal templating, in which monodisperse polymeric particles were trapped in inorganic matrix and then polymer were burned out leaving inorganic porous structures. We have here encapsulated polymer particles inside oil-in-water emulsion with sol-gel precursors of titania. Then, oil phase were slowly evaporated forming composite spheres by heat treatment. Finally, by removing polymer, we have produced ordered macroporus titania particles. We could also modified internal surfaces of pores and adding functional materials for further applications including carbon dioxide capture. |
