Abstract
MnO2 incorporated Ni-P electrodes were prepared by electroless deposition from a solution containing MnO2 particle suspended by stirring. The electrocatalytic activity of the electrode towards ethanol oxidation found to vary with concentrations of MnO2 particles. The electrode with 10 g/L MnO2 particles exhibited maximum electrocatalytic activity. The optimized electrode had a response time of 14 s and a sensitivity of 8.6 μA/ppm cm2. The electrochemical characterization for the catalytic activity was explained by cyclic voltammetry, chronoamperometry. The sensing behavior of the electrode was studied in 0.2 M NaOH solution containing ethanol using impedance spectroscopy. The maximum rate of ethanol oxidation was observed at its sensing potential.
