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溶液的用量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．
The photocatalytic degradation of acetone by supported TiO2 catalysts was studied. The results show that the catalyst and the amount of TiCl4-HCl solution have a significant influence on the catalyst performance at the calcination temperature of carrier and catalyst. XRD, ICP and SEM results show that by changing the preparation conditions. Increasing the content of the active component in the catalyst, improving the crystal form of the anatase TiO2 and decreasing the particle size can all enhance the activity of the catalyst.
