Abstract: Composite oxide catalysts Eu/TiO2, Ce/TiO2, Y/TiO2 (RE/TiO2) were prepared by impregnation method and characterized by means of UV-Vis spectroscopy, TEM and BET. The results indicate that the size of TiO2 has different effect on the modification efficiency. The catalytic activity of micron scale TiO2 increases by 136% and 59% owing to the addition of Y and Ce, respectively, while the catalytic activity of nanoscale TiO2 decreases due to the doping of Y and Ce.
