| Abstract | The electrochemical behavior of NO2 at Au/Nafion, Pt/Nafion and Pt-Au/Nafion electrodes was investigated by using electrochemical and SEM methods, respectively. It was found that the Pt-Au/Nafion electrode showed higher electrocatalytic activity than Pt/Nafion and Au/Nafion electrodes. The net current density of Au/Nafion electrode decayed significantly during the reaction, though it showed high initial value. Pt/Nafion and Pt-Au/Nafion electrodes, on the contrary, showed good stability. A quantitative determination of NO2 concentration was carried out at Pt-Au/ Nation electrode and a satisfactory linear relationship was found for the NO2 concentration in the range of 0 - 100 ppm. |
