ABSTRACT. Inverse spinel Cobalt ferrite (CoFe2O4) nanoparticles has fascinated colossal attention owing to its remarkable photo fenton activity and extra ordinary amalgamation of its properties specially its optical and magnetic properties are catered as suitable candidates in the field of electronics. Their high electrical resistivity prevents induction of eddy currents and the resultant loss of energy. Ferrites are economically viable and their magnetic and optical properties can be tailored as per the requirement of applications. Nanostructured cobalt ferrite particles were synthesised using scalable and facile co-precipitation technique by maintaining pH 9 by using the precursor solution. The particle size, morphology and reaction rate of the nanoparticles could be well tailored. The prepared CoFe2O4 nanoparticles were characterized by X-ray diffraction (XRD) revels the crystalline nature of the synthesized product, PL photoluminescence spectra and UV-Vis Spectroscopy (UV-Vis) divulges the optical properties and the spectrum is further used to evaluate the optical constants required for fabrication and Using, VSM, the magnetic behavior of the material have been determined. Degradation of Methylene blue dye using synthesized sample was studied for photocatalytic application.
