本研究利用溶胶-凝胶法,以硅胶为载体，制备了掺铕TiO2纳米光催化材料。重点研究了钆钛比、焙烧温度及镀膜次数不同时对产物的光催化活性的影响。并以太阳光作为光源，对甲基橙进行了光催化降解试验来评价制备的复合光催化材料的光催化性能。实验表明，其最佳铕钛比为1.0％，焙烧温度为550℃，镀膜次数为2次。

In this paper, a kind of Europium-doped nanoparticle photocatalyst has been synthesized by sol-gel process taking silica gel as carrier. Such factors as the doping proportion of Europium and titanium, the calcinations temperature and time, the film of plating that influence the photocatalytic activity of sample have been discussed in detail. The photocatalytic activity of this nanoparticle was detected by the degradation of methyl orange in sunlight. The experiment indicated that its best Europium titanium ratio is 1.0% ,calcinations for 3 hours at 550℃, the film of plating at 2.
