| 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... |
