摘要
Abstract
Using Sol-Gel method, the photocatalysts of film type TiO2supported on γ-Al2O3 and powder type TiO2 were prepared and characterized by the techniques of XRD , SEM and activity evaluation for photocatalytic decomposition of phenol. The results showed that the complete crystal form of anatase titanium dioxide was formed, when the gel underwent calcinations at the temperature of 500℃ for 3 hours ,and this crystal form of TiO2 as catalyst showed higher activity for photocatalytic decomposition of phenol. The activity of TiO2 film /γ-Al2O3 was superior to that of TiO2 powder.关键词
