In this paper, we report the studies on photocatalytic activity of the zinc ferrite nanoparticles for the degradation of methylene blue dye. The study reveals that an optimum minimum dosage of 1g/L can give a degradation efficiency of 89% within 90 minutes of its exposure to the sunlight. Zinc ferrite nanoparticles were synthesised using co-precipitation method in stoichiometric ratio. Structural, magnetic and optical characterisation were done using XRD, FTIR, VSM and UV-VIS-IR analysis which confirmed the crystalline, magnetic and visible light active nature of the sample. Feasibility for magnetic retrieval of the photocatalyst was studied after photodegradation of dye and then analysed using XRD which confirmed the phase purity of the sample even after retrieval.
