Preparation and Properties of Multiphase Composite Photocatalytic Materials Based on Spindle α-Fe₂O₃ Nanoparticles

Abstract

The spindle-shaped α-Fe₂O₃ was prepared by hydrothermal method, Fe₂O₃/ZnO and Fe₂O₃/ZnO/PANI photocatalytic composite materials were successfully prepared, and their structure and photocatalytic properties were studied. The results show that different amount of PANI has different photocatalytic performance, and the addition of PANI improves the photocatalytic properties of the composite. In addition, Fe₂O₃/ZnO/PANI(10%) exhibits the best photocatalytic performance. After two hours of UV irradiation, the degradation rates of methyl orange and orange II reach 68.1% and 75.4%, respectively.
