利用水热法合成稀土Y( OH)3和Eu( OH)3纳米线,取一定稀土纳米线掺入以钛酸四丁酯为主要原料的溶胶-凝胶体系中,制备出不同煅烧温度不同稀土掺杂量的TiO2材料。以甲基橙为目标降解物,研究了该材料的光催化性能。结果表明,稀土的掺入量对材料的光催化性能有明显的影响,甲基橙的脱色率随着稀土掺入量的增加降低；不同煅烧温度也影响材料的光催化性能,实验条件下,煅烧温度较高的材料催化甲基橙的脱色率更高,当煅烧温度为600℃,Y( OH)3或Eu( OH)3纳米线掺入量为1%时,光催化效果最佳,光反应1 h后甲基橙的降解率可达99%以上。

Using hydrothermal synthesis of rare earth Y( OH) 3 and the Eu( OH) 3 nanowires,taking a cer-tain rare earth nanowires adding tetrabutyl titanate as the main raw material of sol-gel system,the prepara-tion of the quantity of different calcination temperature of rare earth doped TiO2 composite material,deter-mination of the UV-Vis absorption spectrum and fluorescence spectrum. Aiming at the methyl orange deg-radation,studied the photocatalytic performance of the material. The results show that the mixed rare earth quantity has distinct effect on the light catalytic properties,decolorization rate of methyl orange with the increase of amount of rare earth doped;Different calcination temperature of the composite materials also affect the photocatalytic performance,raise the temperature under the condition of laboratory decolorization by rate of methyl orange, when the calcination temperature is 600 ℃, the Y ( OH ) 3 or Eu ( OH ) 3 nanowires doping amount was 1%,photocatalytic effect is best,when light after 1 h of reaction of methyl orange degradation rate can reach more than 99%.
