| Description |
The electrochemical capacitive behavior of NiFe2O4 ceramic powders prepared by
combustion synthesis, polyol-mediated and sol-gel methods was studied. The phase formation
and morphological characterizations of synthesized materials were carried out through thermal
analysis (TG-DTA), powder X-ray diffraction (XRD) and scanning electron microscopy (SEM).
Electrochemical performance of these electrode materials as capacitors were investigated in
aqueous NaCl electrolyte using cyclic voltammetry (CV) and the corresponding specific
capacitance (SC) values were determined. The observed electrochemical double layer capacitive
(EDLC) behavior in NiFe2O4 depends on the morphology which can be controlled by the
synthesis method adopted. NiFe2O4 synthesized by sol-gel method exhibited a specific
capacitance of 97.5F/g which is higher than the capacitance values of NiFe2O4 obtained through
other synthesis methods.
