| 摘 要： | 以纯锐钛矿型和纯金红石型TiO2为原料,通过超声分散制备复合晶态的TiO2,研究纳米TiO2的晶相组成对光催化性能的影响.通过X射线衍射分析表征晶相组成与晶粒尺寸;以甲苯为目标降解物,采用气相色谱检测复合晶态的TiO2对甲苯的降解效果.结果表明:锐钛矿型TiO2的光催化性能明显地优于金红石型TiO2,但由于协同作用,一定比例的金红石能提高纳米多晶TiO2的光催化性能;当晶相中锐钛矿型与金红石型TiO2的质量比为83∶17时,纳米多晶TiO2具有最佳光催化活性.

| Abstract: | Polycrystalline TiO2 was prepared by means of ultrasonic dispersion,with pure anatase and rutile as the raw materials.The effect of crystal phase composition on the photocatalytic activity of the nano-polycrystalline TiO2 was then investigated.In the investigation,XRD was employed to analyze the crystal phase composition and crystal size,and gas chromatography was employed to evaluate the toluene degradation photo-assisted by the nano-polycrystalline TiO2.Experimental results show that,although the photocat... |
