Sugars Electrooxidation at Glassy Carbon Electrode Decorate with Multi-Walled Carbon Nanotubes with Nickel Oxy- Hydroxide

a higher charge-transfer coefficient (0.37) with a diffusion coefficient of 1.3×10 -6 cm 2 s -1 and showed the higher electrocatalytic rate constant of 2.1×10 4 L mol -1 s -1 . The modified electrode exhibited a linear response to sugars concentration in the range around of 2.5×10 -4 mol L -1 to 5.6×10 -3 mol L -1 and limits of detection around of 1.9×10 -4 mol L -1 - 4.3×10 -4 mol L -1 .
