The Influence of Zn Doping on the Cation Distribution and Antibacterial Activity of CoFe2O4

Abstract Nanoparticles of formula Co 1- x Zn Fe 2 O 4 ( = 0.0, 0.3, and 0.5) were prepared successfully using a citrate-auto-combustion method. This work studies the substitution effect 2+ ion on physical, chemical, structural properties CoFe . The structure samples was determined via X-ray diffraction (XRD) Fourier transformed infrared spectrometer (FTIR). investigated ensures that all crystallite into single structure. There is variation size with change in concentration as it observed increased from 16.01 to 30.56 nm by increasing concentration. transform spectra (FTIR) range (390:4000) Cm −1 used for studying elastic spinel ferrites.
