MESOPOROUS SILICA/CERIA-SILICA COMPOSITE AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a mesoporous silica/ceria-silica composite and a method for preparing a mesoporous silica/ceria-silica composite and, more specifically, to a mesoporous silica/ceria-silica composite which is composed of mesoporous silica having a hexagonal or cubic structure and ceria having a hexagonal structure provided on a surface and pores of the mesoporous silica, the oxidation state of the ceria being Ce4+ and Ce3+.
