WC-doped Ni over an active carbon catalyst (Ni-WC/AC), prepared by incipient wetness impregnation, is proposed as an anode for the amplified electrochemical oxidation of glucose in 0.1 M KOH solution. Cyclic voltammetry and morphology characterizations were used to explore these electrocatalysts. It was found that Ni-WC/AC catalysts were nanoparticles with a diameter of 10 nm and the 20%wtNi-20% wtWC/AC catalyst showed superior electrocatalytic activity toward glucose oxidation. The extraordinary activity obtained at the 20%wtNi-20% wtWC/AC modified glass carbon electrode (GCE) is attributed to the synergistic effect between Ni and WC toward glucose electroxidation.
