摘要: 采用溶胶凝胶法制备了不掺杂、V 掺杂、Ce掺杂、V/Ce共掺杂纳米TiO2光催化剂，并将其分别负载于瓷砖上，利用X射线衍射分析（XRD）和扫描电镜分析（SEM）技术对薄膜样品的结构和形貌进行了表征。通过对甲醛的降解实验评价光催化剂的光催化活性。实验结果表明，光催化剂的负载量、共掺杂离子的掺杂量、掺杂配比、煅烧温度影响纳米TiO2的光催化活性。V/Ce共掺杂TiO2光催化剂产生了协同效应，其光催化活性优于纯TiO2和单掺杂TiO2样品。

Abstract: The Un-doped， V single-doped， Ce single-doped， and V/Ce co-doped TiO2 were prepared by sol-gel method， and then loaded on the faces of enamel tiles， the structure and morphology were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). Their photocatalytic properties were studied by photocatalytic degradation of formaldehyde. The results indicated that the photocatalytic activity of the co-doped TiO2 was mainly affected by factors such as loadings， doping content， doping ratio and calcinate temperature. The V/Ce co-doped TiO2 showed a synergistic effect for photocatalytic activity， which made the photocatalytic activity higher than that of single doped TiO2 and un-doped TiO2.
