| 摘 要： | 以钛酸丁酯为原料,采用溶胶-凝胶法制备TiO2粉体。利用X射线衍射谱、拉曼光谱、红外光谱、扫描电子显微镜和紫外-可见光分光光度计分别研究煅烧温度对TiO2粉体的微观结构、颗粒形貌与紫外光光催化性能的影响。实验结果表明:随着煅烧温度的升高,TiO2粉体发生了锐钛矿到金红石结构的相变,相变温度大约在623K~673K,且等轴状颗粒的尺寸逐渐增加。同时发现锐钛矿结构的TiO2粉体对甲基橙的紫外光光催化活性最高,而无定形及金红石结构不利于粉体的紫外光光催化活性。

| Abstract: | By using tetrabutyl titanate as source precursor,TiO2 powders were prepared by Sol-gel method.The influence of calcination temperature on the microstructure,morphology and photocatalysis properties of TiO2 powers were investigated by means of X-ray diffraction,Laman spectra,FTIR spectra,scanning electron microscopy(SEM) and ultraviolet radiation-visible(UV-vis) spectrophotometer,respectively.The results showed that TiO2 powers had a phase transitions from anatase to rutile with increasing calcination temper... |
