Abstract
Nickel doped manganese tetroxide (Mn3O4) nanoparticles are synthesised by microwave assisted solvothermal route. The structural characterisation of as prepared Ni doped Mn3O4 nanoparticles are determined by the aid of powder X-ray diffraction (XRD). The functional groups present in the material are determined by Fourier transform infrared (FTIR) analysis. The transmission electron microscope (TEM) images showed the topographical, compositional and crystalline information. Energy-dispersive X-ray (EDX) analysis determines the abundance of specific elements. The optical properties are analysed by ultraviolet-visible (UV-Vis) spectroscopy. The perceived red shift in the UV-Vis absorption spectra confirmed the stimulated electron-phonon interaction in nickel doped Mn3O4 nanoparticles. The electrochemical characteristics of nickel doped Mn3O4 nanoparticles are examined by cyclic voltammogram (CV). The vibrating sample magnetometer (VSM) studies confirmed the ferromagnetic behaviour of Ni doped Mn3O4 nanoparticles at room temperature.
