摘要
为提高二氧化钛的光降解作用,通过溶胶-凝胶法,用钛酸丁酯为前驱物,并首次用钼酸铵为钼源合成出了纳米TiO2颗粒和新型的纳米Mo/TiO2复合粉体.结果显示:这种钼掺杂的改性后的二氧化钛提高了二氧化钛的分散性;新材料在光照下对罗丹明B有很好的光降解作用,其降解率在3 h内接近100%.
To improve the effects of TiO2 on photocatalytic degradation, using Ti ( OC4H9 ) 4 as raw material and ammonium molybdate as molybdenum source for the first time, nano-TiO2 and new nano-sized Mo/TiO2 particles were prepared via sol-gel process. The results indicate that the composite powders of the modified Mo-doped TiO2 improve the dispersion of the TiO2 particles;Mo/TiO2 shows a good effect on the photocatalytic degradation of rhodamine B solution under UV lamp irradiation, and the degradation rate reaches nearly 100% within 3 hours.
