Synthesis and characterization study of dual phase mixed zinc cobalt ferrite nanoparticles prepared via chemical co-precipitation method

Nanoparticles of Zinc substituted Cobalt ferrite powders having general formula ZnxCo1-xFe2O4 (x = 0, 0.25, 0.5, 0.75, 1.0) have been produced by using analytical grade nitrates and hexadecyltrimethylammonium bromide (CTAB) as structure directing reagent via Chemical co-precipitation method. The morphology prepared polycrystalline nanoparticles were investigated X-ray diffraction (XRD), Fourier Transform Infrared Radiation (FTIR) Scanning electron microscopy (SEM) respectively. Thermogravimetric differential analysis (TG/DTA) technique gives information about phase formation occurs beyond 450 ºC. XRD confirms the establishment cubic spinel with presence minor secondary α-Fe2O3 (hematite) at a calcination temperature 650 mixed zinc cobalt showed dual crystallite size lies in range 6-11 nm. FE-SEM microstructure shows nearly spherical particle between 0.11-0.20 µm. FT-IR spectra display two significant strong absorption bands nearby 400 cm-1 600 on tetrahedral octahedral sites Copyright © 2018 VBRI Press.
