Background: To meet the challenge of rising demand for energy, at the same time, reducing
environmental pollution, the energy synthesis through electrochemical oxidation of fuels, in fuel
cell is a promising alternative green energy technology. Development of fuel cell lies on exhaustive
research on development of high energetic electro catalytic electrodes over which fuels break to produce
free electron and ions, delivering the electrical energy.
Methods: The present work aims at developing two electrocatalytic materials: NiO and MnO2, both
impregnated with Nano Carbon by electro synthesis method. Sugar cane is an abundantly grown
crops, having 65-75% of sugar, in the form of sucrose. The performance of the materials were investigated
by electrochemical characterization: cyclic voltammetry, chronoammetry, polarization tests
and impedance spectroscopy.
Results: The materials were found to deliver a high current on electro oxidation of sugar cane syrup.
The effect of Nano carbon on NiO and MnO2 has enhanced the current to a level of over 100mA/cm2.
XRD study showed the presence of metal oxides and carbon. The electron microscopy images revealed
fine grain oxides with entrapped nano carbon. The carbon seems to be in the form of graphene,
produced during electrochemical exfoliation at anode. The SEM morphology of enhanced 3D
surface area with high energetic graphene phase entrapped with fine structure metal oxides, account
for the high current obtained by electro oxidation of the fuel.
Conclusion: The present investigation opens up a new way and technology of producing energy at a
economically viable rate, compared to conventional electrical energy production The materials developed
are found to be very good energetic electrodes for future fuel cell in automotive industry.
