Electrochemical Oxidation of Biofuels Derived from Mango Wood Floor on Electrolytically Developed MnO2 Electrode to Produce Renewable Electrical Energy in Fuel Cell | Bentham Science

摘要

Background: To cope up with the rapid growth of cities, automation, computation, at thesame time, the global pollution level for increasing combustion of fossil fuels to energy, the need ofhour is to find an alternative energy resource from renewable fuels.Methods: Glucose and alcohol based biofuels were produced from pretreated mango tree wood floorby enzymatic saccharification and fermentation. It was found that pretreatment of the biomass has astrong effect on the quantity of the fuel produced. The fuel converted by enzymatic saccharificationwas a glucose based fuel, while that by fermentation was an alcohol based fuel.Results: The quantity of fuel produced was estimated as the amount oxygen required for its fullcombustion (COD mg/l). The COD was higher for the alcoholic based fuel than the former one. Boththe fuels could be converted to pure electrical energy by electrochemical oxidation on aelectrolytically developed MnO2. The MnO2 anode was produced by electrolytic decomposition fromMnSO4 solution.Conclusion: This inexpensive electrode outperformed the well known Pt electrocatalytic material anddelivered a current density in the range of 5-12 mA/cm2.
