| Abstract: | Taking Ti(OC 4H 9) 4 as raw material and using the precipitation method,the TiO 2 catalyst was prepared and used for photocatalytic degradation of cation-dye.The effects of making conditions of catalyst on the degradability of TiO 2 were investigated.The results showed the optimal preparation parameters:sedimentation pH was 8.0,the particle sizse of the catalyst was less than 200 mesh,firstly using distilled water washing,then using absolute alcohol washing,calcination temperature is 500℃.Using this catalyst,the degradation rate of cation-dye was more than 87% during 30 minutes irradiation. |
| Keywords: | potocatalysis cation-dye degradation TiO 2 catalyst and development |
