| 摘 要： | 以尿素作为氮源,盐酸(HCl)为钛酸丁酯(TBT)的保护剂,采用溶剂热法合成氮掺杂TiO2微球。用扫描电镜、X射线、能谱仪、多功能电子能谱仪、紫外-可见分光光度计等手段表征了盐酸加入量对微球形貌、物相、成分和催化性能的影响。实验结果表明该方法不仅能合成形貌较好的TiO2微球,同时实现了氮掺杂;盐酸加入量对微球形貌、物相和催化性能有较大影响,发现m(HCl)∶m(TBT)为2.6∶1时光催化效果最佳,在紫外灯和可见灯照射下催化效率均超过Degussa P25。

| Abstract: | Nitrogen-doped TiO2 microspheres were prepared by solvothermal process in ethanol,hydrochloric acid(HCl) and tetrabutyl titanate(TBT) using the urea as a nitrogen source supplier.Based on XRD,SEM,EDS,XPS,UV-Vis techniques we systematically observed the effect of the hydrochloric acid.The results showed urea can be used as a nitrogen source supplier to prepare nitrogen-doped TiO2 microspheres;the addition of hydrochloric acid really influences the character of TiO2 microspheres.When the m(HCl)∶m(TBT)=2.6∶1,the photocatalytic activity is higher than Degussa P25. |
