| 摘 要： | 纳米TiO2是一种重要的半导体光催化剂,在众多领域具有广阔的研究及应用前景。以稀土Ce为掺杂元素,采用溶胶-凝胶法制备了Ce掺杂纳米TiO2(纳米Ce/TiO2),通过XRD、BET、SEM等技术对其进行表征。设计L9(34)正交实验研究了不同条件对纳米Ce/TiO2的结构及表面特征的影响,优化了纳米Ce/TiO2的制备条件。初步研究了Ce/TiO2的光催化抗菌性能,表明Ce掺杂能够改善纳米TiO2的光催化抗菌性能。

| Abstract: | Nano-TiO2 is an important semiconducting photocatalyst,with a broad study and application prospect in many material fields.In this paper nano-TiO2 crystal doped with Ce(Ce/TiO2) was prepared by the sol-gel method.The crystal samples were characterized by XRD,BET and SEM.Through L9(34) orthogonal experiment,four factors related to the structural properties of Ce/TiO2 were studied,and the best condition to prepare the Ce/TiO 2 was found as a result.Preliminary experiments of Ce/TiO2 show that antibacterial properties of TiO2 can be improved by doping with Ce. |
