Transition Hausmannite Nanoparticles Embedded on Uniform Carbon Micro Spheres Synthesis for Electrochemical Examination

Abstract

Carbon spheres wrapped by maghemite nanoparticles were synthesized through facile hydrothermal method. The structural parameters were analyzed through powder x-ray diffraction analysis. Functional groups were analyzed by Fourier transform infrared spectroscopic analysis. The prepared carbon spheres wrapped by maghemite nanoparticles morphology were investigated using scanning electron microscopic analysis. The elemental composition and distribution of elements were examined by energy dispersive spectroscopic technique with mapping. Redox property, charge discharge mechanism was done through cyclic voltammetry and galvanostatic charge-discharge studies.
