Abstract In order to solve the problems of low efficiency and high cost of catalyst in the treatment of phenol-containing wastewater by traditional photocatalytic technology, a new composite material of α-Fe2O3/TiO2 was prepared by high temperature calcination. The prepared materials were characterized by X-ray diffractometer and other instruments, and their photocatalytic degradation of phenol was studied under the irradiation of 500W high voltage mercury lamp. The results of XRD and SEM showed that the composite material was successfully prepared, and the nano-α-Fe2O3 was attached to the nano-TiO2 to form a heterostructure. FT-IR and UV-Vis detection showed that the composite material had good photocatalytic performance, its visible light absorption range was obviously widened, and the band gap was narrowed (2.02 eV to 1.81 eV). The specific surface area and pore volume were calculated to be 66.4725 m2/g and 0.3213 m3/g by BET test, which were much higher than that of single catalyst, further indicating that the photocatalytic performance of the composite was better than that of α-Fe2O3. In addition, the factors such as the composite ratio of α-Fe2O3 to TiO2, the dosage of composite material, the concentration of phenol, pH and illumination time were optimized. The results show that the degradation efficiency of phenol can reach 94.79% in case that the test solution with phenol concentration of 20 mg/L and pH = 8, a dosage 0.6 g/L of the composite material with a mass ratio 1∶10 for α-Fe2O3 to TiO2 is adopted under the illumination of high voltage mercury lamp for 120 min. Which is much higher than that of single material.
