摘要：
The electrooxidation behavior of 4-aminoquinaldine (AQ) in H2SO4 was investigated by sweep potential method. The resulting polymeric film has poor redox response in NaCl aqueous electrolytic solution. After soaking the polymeric film in CuCl2 aqueous solution for 45 minutes, the resulting loaded polymer film has a dramatic waves when tested in the same electrolytic solution. A well defined redox response was obtained and exhibited a thin layer behavior. The electrocatalytic activity of the modified electrode for the oxidation of methanol, propanol and formaldehyde in aqueous acidic solution was studied by using cyclic voltammetry. Results showed that, poly AQ/Pt modified electrode can improve the activity of Pt towards the oxidation of these small organic molecules, showing the possibility of attaining good electrocatalytic anodes for fuel cells.
