负载型TiO2催化剂的制备及光催化丙酮蒸汽的降解性能研究

研究了负载型ＴｉＯ２催化剂对丙酮的光催化降解作用。结果表明，载体和催化剂的灼烧温度，ＴｉＣｌ４－ＨＣｌ溶液的对催化剂性能有较大的影响。ＸＲＤ，ＩＣＰ和ＳＥＭ等结果表明，通过改变制备条件，增加催化剂中活性组分含量，改善锐钛矿型ＴｉＯ２晶形，减小粒径，均能使催化剂活性加强。

Study on the Preparation of Supported TiO_2 Catalyst and Photocatalytic Degradation of Acetone

In this work photocatalytic degradation of acetone on supported TiO2 catalyst was studied.The catalysts were characterized by XRD, ICP and SEM methods. ExperimentaI results show that the calcination temperature and the volume of TiCl4-HCl has great effect on the catalyst performance. Increasing the quantity of active component, improving anatase TiO2 crystal form, and decreasing particle size all increase the catalytic activity.
