【Abstract】 A novel carbon atom wire modified electrode was studied by cyclic voltammetry in 9 electrolytes within the pH range of 1.55～10.56 and the electrochemical responses were observed. In the pH 6.80 phosphate solution, the anodic peak potential of 1mM NADH on the modified electrode shifted negatively by 0.390?V and the anodic peak current increased 4.1 times compared to those on the bare glassy carbon electrode, showing the outstanding electrocatalytic activity of the carbon atom wire modified electrode.更多还原
