| Abstract: | A new TiO_2 photo-catalyst was prepared by Sol-Gel technique using honeycomb ceramics as supporter. The effect of preparing process on catalytic activity of TiO_2 photo-catalyst was studied. Results show that the catalyst fired at 500℃, with 5 layers of TiO_2 film on honeycomb ceramics appears high catalytic activity. Under UV radiation, 100% of o-chlorophenol in the solution of 1.0×10~(-3)mol/L was photo-catalytically degraded by this catalyst in 2.5 h, and with the cooperation of O_3, o-chlorophenol was full degrades in 1.5h. |
| Keywords: | honeycomb ceramics TiO_2 photo-catalyst o-chlorophenol |
