| 摘 要： | 以钛酸丁酯、无水异丙醇、钒酸铵和氯铂酸为原料,采用so l-gel法合成了复合催化剂V-T iO2、P t-T iO2和V-P t-T iO2.XRD、SEM和UV-V is研究结果表明:V、P t对T iO2的晶型影响不大,但对其形貌和紫外可见吸收有影响.考察了复合催化剂对三氯乙酸的光催化降解活性,结果表明:V、P t均能提高其催化活性,而且V和P t之间能协同大幅度提高其催化活性,并对产生该结果的原因进行了探讨.

| Abstract: | Using Ti(OBu)_4,H_2PtCl_6 and(NH_4)_3VO_4 as raw materials,V-TiO_2,Pt-TiO_2 and V-Pt-TiO_2 were prepared via Sol-gel method.The catalysts were characterized by XRD,SEM and UV-Vis spectra.Activities of the photocatalysts were evaluated by photodegradation of Cl_3CCOOH.The result shows that the V and Pt do not change the morphology of the titanium.But they can effect the visage and the UV-Vis spectra of the titanium.Activities of the photocatalysts are obviously enhanced when titanium were codoped with V and Pt.The reasons are discussed simply. |
