| Abstract: | In order to get higher photocatalytic performance under visible light,the different ions（La3＋ 、Ni2＋ 、Ce3＋） were added into the TiO2 sol,and the photocatalytic activity of TiO2 was studied too.The result showed that photocatalytic property can be improved by adding suitable dosage of ions.La3 ＋-doped TiO2 had the highest photocatalytic property,Ni2 ＋-doped TiO2 was the second,and Ce3 ＋-doped TiO2 was the lowest of all. |
