Preparation and characterization of nickel ferrite nano particles by co-precipitation method with citrate as chelating agent

In this era, the latest trend in materials science and related fields is fabrication, characterization and applications of nano materials. In the present study, NiFe2O4 nano particles were synthesized by co-precipitation method with citrate as chelating agent. The synthesized materials were calcinated at different temperatures 400, 600 and 800 degrees C and characterized by using XRD. The NiFe2O4 nano particles calcinated at 600 degrees C were characterized by using FE-SEM with EDAX, FE-TEM with SAED pattern, DLS Zeta Potential and CV. The formation of single phase nanosized nickel ferrite was investigated by XRD and the particle size linearly increased with the temperatures was noticed. The surface morphology of NiFe2O4 studied by FE-SEM was cubic spinel structure and it was confirmed by FE-TEM. The element identified in the NiFe2O4 nanoparticles from EDAX analysis were Fe, Ni and O. Stability of the particle was analysed through Zeta potential study. Capacitance value 123 Fg(-1) was observed from CV study and it was suitable for super capacitance application.
