Pt-Ni-Cu nanoparticles decorated glassy carbon electrode for glucose electro oxidation process

Platinum and nickel-copper nano particles were electrodeposited on glassy carbon electrode using cyclic voltammetry-based electroplating technique. Morphology and chemical composition of the newly designed electrode was studied via SEM, EDX and elemental mapping analysis. This electrode was eventually employed to electro-oxidize of glucose using cyclic voltammetry and electrochemical impedance spectroscopy (EIS) techniques. The results revealed high catalytic activity of the Pt-Ni-Cu/glassy carbon electrode. Compared to the other electrodes reported in the literature, Pt-Ni-Cu/glassy carbon electrode shows a better potential as an anode for direct glucose alkaline fuel cells.
