Electroless Deposition of the Ni Nanoparticles on the Graphite Electrode for Glucose Oxidation

Battery graphite rod was modified with Ni nanoparticles with a new electroless procedure and the performance of the proposed electrode was evaluated as a non-enzymatic anode for electrocatalytic oxidation of glucose in alkaline media. Glucose fuel cells that use enzymes or microorganisms catalysts are limited by their extremely low power output and rather short durability. The structure and morphology of the electrode surface were examined with X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX) and scanning electron microscopy (SEM) techniques. Voltammetric and amperometric studies indicated that the onset potential of the glucose oxidation is low (~ 0.3 V) and the electrode stability is good. In addition to these advantageous, due to easily preparation and low cost, it will be used probably in glucose fuel cells as an anode
