A novel modified electrode was fabricated by intercalated CNT-Pt in the surface of waxed graphite, which provided excellent electrocatalytic activity and selectivity for both oxidation and reduction of hydrogen peroxide. The current response of the modified electrode for hydrogen peroxide was very rapid and the detection limits in amperometry are 2.5×10^-6 mol/L at reduction potential and 4.8×10^-6 mol/L at oxidation potential. It was desmonstrated that the electrode with high electro-activity was a suitable basic electrode for preparing enzyme electrode.展开更多
