Saad M. Alshehri, Ameen N. Alhabarah, Tansir Ahamad, Jahangeer Ahmed, Tokeer Ahmad
Nitrogen-doped CoFe2O4/C (NCFC) nanocomposites (NCs) with an average size of 10 nm were obtained from the polymeric route, using egg white albumin followed by firing at 700 °C/3 h under the flow of helium gas. Structural and morphological studies of prepared materials were investigated by using powder X-day diffraction, X-ray photoelectron spectroscopy, and electron microscopic techniques. NCFC-NCs exhibit excellent supercapacitive performances compared to pure MFe2O4 nanoparticles (M=Ni, Co, Cu, etc.). The specific capacitance (Cs) of NCFC-NCs was found to be approximately 474 F/g, which is around five times higher than that of pure CoFe2O4 nanoparticles (Cs=94 F/g) at a scan rate of 5 mV/s in 5 M KOH. The energy densities of NCFC-NCs and pure CoFe2O4 nanoparticles were found to be about 116 and 23 Wh/kg, respectively. Galvanostatic charge−discharge measurements of NCFC-NCs reveals the loss of less energy and the discharge time of the nanocomposites was found to be approximately ten times higher compared to pure CoFe2O4 nanoparticles for 50 segments. The stability tests of the materials were also carried out by the cyclic voltammetry, chronoamperometry, and chronopotentiometric measurements for the purpose of industrial applications. Debut performance: Nitrogen-doped CoFe2O4/C nanocomposites (NCFC-NCs) with an average size of 10 nm are obtained by using a polymeric route. Structural and morphological studies of the prepared materials are carried out by using powder X-day diffraction, X-ray photoelectron spectroscopy, and electron microscope techniques. In addition. the NCFC-NCs exhibit excellent supercapacitive performances compared to pure MFe2O4 nanoparticles (M=Ni, Co, Cu, etc.).
