Synthesis and photocatalytic investigation of ZnFe2O4 in the degradation of organic dyes under visible light

Zinc ferrites (ZnFe2O4), with spinel-like structure, were produced by combustion reaction synthesis in solution and heat-treated at temperatures of 400–1100 °C. The structural and chemical properties of the ZnFe2O4 samples were investigated by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FT-IR), Field Emission Gun Scanning Electron Microscopy (FEG-SEM) with X-ray dispersive spectroscopy (EDS), and diffuse reflectance...
