High photocatalytic activity TiO2 photocatalysts were prepared using titanium(IV) sulphate as the precursor by liquid-phase precipitation method. X-ray diffraction and TEM were employed to characterize the morphology, structure of the photocatalysts. Photocatalysic activity of TiO2 prepared by this method was investigated using photocatalytic degradation of methyl red (MR) under UV and visible-light (VL) irradiation as the model reaction. The results indicated that the highest catalytic activity TiO2 catalyst was prepared under 700°C calcination for 4h. The optimum decoloration rate of simulated dyeing wastewater for MR reached to 95% and 98% after UV and visible-light illuminating for 30 min and 140min respectively.
