OXIDE COMPOSITE MATERIAL AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an oxide composite material consisting of an inorganic porous body with pores into which a relatively large amount of oxide nanoparticles are introduced and its production method and to provide an oxide composite material having a spherical shape having a monodisperse distribution and its production method.

SOLUTION: The method for producing the oxide composite material comprises a first impregnation process in which the pores of the inorganic porous body are impregnated with a first solution comprising a metallocene or its derivative dissolved in a first solvent which is polymerized by heating, a polymerization process in which the first solvent is polymerized by heating the porous body and a first heat-treatment process in which the inorganic porous body is heat-treated at 400°C or higher in an atmosphere containing oxygen so that the metallocene or its derivative is thermally decomposed so as to produce a first metal oxide. The oxide composite material is produced with the method.
