N2 - Activated carbon (AC) supported titanium dioxide (TiO2) photocatalyst (TiO2/AC) was prepared by two-step solgel process. Crystal structure, and surface morphology of TiO2/AC were characterized by X-ray diffraction (XRD), N2 adsorption-desorption isotherm measurements (BET) and scanning electron microscopy (SEM), respectively. The results show that average crystal size of TiO2 in 11% TiO2/AC catalyst is 17.6 nm and special surface area of AC carrier is 887.11 m2/g. The photocatalyst has highly developed microporous structure, improves the dispersion degree of TiO2, and decreases the size of aggregate. Meanwhile, TiO2/AC was applied to degradate organic pollutants in purified terephthalic acid (PTA) wastewater.The obtained optimum conditions of photocatalytic degradation are as follows: the mass amount of TiO2 loaded on AC is 11 %, the usage amount of catalyst is 7 g/ L wastewater and reaction time is 7 h. Under the optimum conditions, the COD removal ratio of wastewater is up to 64.30 %.
