ZnFe2O4 nanoparticle: Synthesis and photocatalytic activity under UV-Vis and visible light

In the present work, the ZnFe2O4 nanoparticle has been successfully synthesized. The obtainedsample was characterized by X-ray diffraction (XRD) and emission scanning electronmicroscopy (FE-SEM) and its optical property were examined by UV-Vis spectrophotometer.FE-SEM revealed that the particle size of the ZnFe2O4 of about 47 nm was synthesized. Thephotocatalytic performance under UV-Vis and visible light was evaluated by decolorization ofcongo red (CR) anionic dye solution. The UV-Vis and visible light irradiation source consist of ahigh pressure mercury lamp 400 W and filament tungsten lamp 100 W respectively. Thephotocatalytic results show that the ZnFe2O4 sample can degrade (CR) dye solution up to 100%after 30 and 120 min under UV-Vis and visible irradiation respectively.
