摘要 以尿素为氮源,利用钛酸四丁酯水解,通过溶胶-凝胶法和水热法制备了N-TiO2纳米粒子。通过X射线衍射、扫描电子显微镜、傅里叶变换红外光谱、荧光光谱、X射线光电子能谱等表征手段对所制材料进行了表征。分析结果表明,所制N-TiO2材料粒径约为20nm,与纯TiO2相比,材料的光电复合能力明显下降。以4N-TiO2-500为最合适的光催化剂对罗丹明6G进行了模拟光降解实验。实验结果表明,制备的材料具有很好的光催化降解能力,在500W高压汞灯光照下,经过120min,罗丹明6G的降解率能达到99.24%。通过对催化剂的耐久性进行研究,发现所制材料经6次循环其光降解率仍高达85.79%。

Abstract: Carbamide was used as the source of N and tetrabutyl titanate as the source of Ti,by the sol-gel method to prepare N-TiO2,and it was characterized by scanning electron microscope (SEM),infrared Spectroscopy (IR),X-ray diffraction (XRD),X-ray photoelectron spectroscopy (XPS) and fluorescence spectra.The results showed that the size of N-TiO2 was about 20nm.Photoelectric ability of the composite was greatly reduced compared with the pure TiO2.4N-TiO2-500 as the most suitable photocatalyst,the photodegradation of Rhodamine 6G was simulated.The experiment indicated that the sample had a great ability of photocatalytic degradation.After irradiated by 500W high pressure mercury lamp,the degradation rate reached to 99.24%.By studying the catalyst durability,it was found that the rate of photocatalytic degradation of prepared material was up to 85.79% after 6 cycles.
