Synthesis and Characterization of Nano-CeO2/TiO2 Mesoporous Composites

Abstract

Abstract: Nano-CeO₂/TiO₂ mesoporous composites were prepared by a structural guide-supercri-tical
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
nano-TiO₂ particles in the anatase structure and have the obvious enhancement effect.

Key words: nanopaxticles of rare earth, mesoporous TiO₂, composite, enhancement effect
