摘要
Nano-Yb2O3/TiO2 particles were prepared by sol - gel method. The properties of the sample were characterized by XRD, TG-DTA, TEM and BET. It was found that the Yb2O3/TiO2 fine particles appeared as a anatase structure with a size smaller than 15 nm below 400degreesC, the BET surface area is bigger than 107.22 m(2). g(-1). If the annealing temperature was over 400degreesC, the particles appeared as the composite structure of anatase and rutile and the grain size of TiO2 nanoparticles increased rapidly, and appeared rurtile structure completely at 800degreesC.
