Abstract
In the present work, the ZnFe2O4 nanoparticle has been successfully synthesized. The obtained sample was characterized by X-ray diffraction (XRD), emission scanning electron microscopy (FE-SEM) and its optical property was examined by UV-Vis spectrophotometer. FE-SEM revealed that the particle size of the ZnFe2O4 of about 47 nm was synthesized. The photocatalytic performance under UV-Vis and visible light were evaluated by decolorization of congo red (CR) anionic dye solution. The UV-Vis and visible light irradiation source are a high pressure mercury lamp, 400 W and filament tungsten lamp 100 W respectively. The photocatalytic results show that the ZnFe2O4 sample can be 100% degrading (CR) dye solution after 30 and 120 min under UV-Vis and visible irradiation respectively
