摘要
通过简单的水热反应,和后续的退火处理得到锐钛矿/TiO2(B)异质结构纳米线。通过XRD、SEM和TEM对其进行表征。并对锐钛矿/TiO2(B)进行甲基橙紫外光降解性能测试,探究和讨论了H2O2对其光催化性能的影响,实验表明当加入1.6mL H2O2时对体系光催化促进效果最优,只需要8min分解率达到99%,降解时间只为无H2O2时的1/5。
Anatase TiO2/TiO2 （B） heterostructure nanowires were prepared by a simple hydrothermal synthesis and post-treatment of titanate nanowires. The as-prepared samples were characterized with X-ray diffraction（XRD）, scanning e- lectron microscope（SEM） and transmission electron microscopy（TEM）. Photocatalytic activity of the nanowires for the degradation of methyl orange（MO） under UV-light irradiation was tested. And the effects of H2O2 on the photocatalytic activity were investigated and discussed. The results indicated that the photocatalytic activity was the best when 1.6ml H2O2 was used. The degradation rate of MO could reach 99% after only 8min, which was much shorter than the degradation without H2O2.
