| Abstract: | A stannic oxide modified microcyclinder carbon fiber(SnO2/C)electrode was constructed using organic chemical vapor deposition technique. The surface morphology and stability of C/SnO2 electrode were discussed and the electrochemical behavior of phenols on the electrode was studied by cyclic voltammetry. The electrode shows significant electrocatalytic activity to the oxidation of phenols and prevents the electrochemical polymerization of phenols on it. The amperometric response to 3-chlorophenol increases linearly with increasing concentration from 2×10-6 to 1.2×10-5 mol/L. |
