Synthesis and Characterization of Nano-CeO_2/TiO_2 Mesoporous Composites

Xu Zhang

Abstract

Nano-CeO2/TiO2 mesoporous composites were prepared by a structural guide-supercritical fluid drying(SCFD)-intrusive precipitation method . The obtained composites were characterized by useing TEM, XRD, BET and BJH etc. techniques, and the composites were used in photocatalyzing and breaking down bright red 3B dye in water and in the waterfree electrorheological (ER) suspensions. The results show that the photoelectricity properties of the composites formed by assembling nano-CeO2 in the pore space of mesoporous TiO2 are different from nanoTiO2 particles in the anatase structure and have the obvious enhancement effect.
