The photocatalytic activity of the catalyst towards dichlorvos has been examined as function of TiO 2 amount, calcination temperature of precursor, pH of sample solution and added amount of H 2O 2. The results indicated that the catalyst prepared by calcination at 200 ℃ showed the highest activity and 89% of Dichlorvos in concentration of 1.0×10 -4 mol/L could be degraded over the catalyst under sunlight illumination for 6 hours.展开更多
