Abstract
Flake shaped ZnFe2O4 nanoparticles have successfully been prepared by co-precipitation method. The phase and crystallinity of the synthesised ZnFe2O4 nanoparticles were studied by XRD. The SEM result reveals that the flake shaped entities are formed by the combination of rod-shaped nanomaterial. The band gap of the synthesised ZnFe2O4 nanoparticles is found to be ∼ 2.14 eV by UV-Vis DRS measurements indicating thereby that this material absorbs visible light (λmax = 579.37 nm). The ferrite nanoparticles were successfully employed as a photocatalytic materials for the degradation of the dye Malachite green (MG) in aqueous medium with ∼ 99% efficiency under visible light irradiation.
期刊介绍：
Materials Research is constantly evolving and correlations between process, structure, properties and performance which are application specific require expert understanding at the macro-, micro- and nano-scale. The ability to intelligently manipulate material properties and tailor them for desired applications is of constant interest and challenge within universities, national labs and industry.
