| 摘 要： | 采用水热法制备钛酸钠纳米管,并用透射电子显微镜(TEM)、分光光度计、X射线衍射仪(XRD)、表面光电压仪(SPS)等对焙烧温度对其光电和光催化性能的影响进行了研究。结果表明,表面光电压谱的响应阈值随温度的升高先红移后蓝移,这是因为焙烧引起钛酸钠纳米管的形貌和晶体类型发生变化。所制样品对甲醛的降解特性测试结果表明,焙烧温度对样品的光催化活性有一定程度的影响。

| Abstract: | Sodium titanate nanotubes prepared by hydrothermal method are characterized by TEM、spectrophotometer、XRD and SPS.The results indicate that the response threshold value of photovoltage initially red shift and then blue shift with the temperature increase.It maybe is caused by the change of morphology and crystalline structure of sodium titanate nanotubes.The results of photocatalytic degradation of formaldehyde by spectrophotometric determination show that the photocatalytic activity is affected by the annealing temperature. |
