Abstract
Co0.5Zn0.5Fe2O4/AgBr hybrids with p-n heterojunction were prepared by a facile sol-gel and hydrothermal method. And the samples with different AgBr contents were characterized by XRD,11X-ray diffraction. SEM,22Scanning electron microscope. UV–vis DRS33UV–vis diffuse reflectance spectrum. and FT-IR.44Fourier transfer infrared spectroscopy. The degradation capability of the photocatalysts were evaluated under visible light and used methyl orange (MO) as a target contaminant. All the composites possessed the magnetic properties of Co0.5Zn0.5Fe2O4 and also exhibited high photocatalytic activity of AgBr. Among the prepared photocatalysts, the hybrids prepared with 0.5g AgNO3 exhibited the highest photocatalytic efficiency. The increase photocatalytic activity of Co0.5Zn0.5Fe2O4/AgBr hybrids might be associated with the formation of suitable internal structures between Co0.5Zn0.5Fe2O4 and AgBr. And a possible photocatalytic mechanism of the Co0.5Zn0.5Fe2O4/AgBr hybrids was proposed.
