| 摘 要： | 采用Sol-gel法制备了V-La共掺杂纳米TiO2光催化剂,XRD结果表明,制备的催化剂为锐钛矿型.以甲基橙水溶液为模拟对象,分别从光照时间、催化剂用量、酸度大小三个方面考察了复合光催化剂的光催化活性,结果表明,V-La共掺杂纳米TiO2光催化剂的光催化活性均高于单掺或不掺杂催化剂.

| Abstract: | In the article, V-La codoped Nano-TiO2 catalyst was prepared through Sol-gel method and the structure of the TiO2 was found to be that of anatase by XRD. Photo-catalytic degradation of Methyl orange aqueous solution under ultraviolet radiation was investigated from the lighting time, catalyst dosage and acidity respectively. The result indicates that the photo- catalytic activity of V-La codoped nano-TiO2 is higher than other catalysts. |
