【Abstract】 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.更多还原
