摘要：
Herein, MIL-101(Fe)@BiOI composites have been synthesized by hydrothermal method and then calcined to get BiFeO3@Fe2O3@BiOI composites with high photocatalytic capacity. The composition, structure, and morphology of the composites were characterized by X-ray diffraction, scanning electron microscopy, and UV-Vis diffuse reflection absorption spectroscopy. The effects of composite ratio (mass ratio), pH, and concentration on photocatalytic performance were studied. Electrochemical impedance spectroscopy, photocurrent response, and Mott-Schottky curve test and analysis show that BiFeO3@Fe2O3@BiOI shows stronger photocurrent response and lower charge transfer resistance. The degradation activity of BiFeO3@Fe2O3@BiOI showed the highest in neutral conditions with a removal efficiency of 81% when the mass ratio was 1:1:1.
