Abstract

Crystallized CeO₂-TiO₂ composite nanostructures were prepared by surfactant-assisted method using mixed solution of alkoxides at 353 K. The morphology and crystalline structure of CeO₂-TiO₂ composite were varied with changing the mole ratio of cerium n-butoxide/tetraisopropyl orthotitanate. These nanostructured materials after calcinations showed reaction activity to oxidize I^- to I₂ owing to Lewis acid sites without irradiation of light.
