A new heated nickel oxyhydroxide covered nickel wire electrode (HNONE) was fabricated and AC heating circuit was used to heat the electrode. Furthermore, the improved electrocatalytic activity of the HNONE for methanol oxidation at elevated electrode temperature was demonstrated. A detection limit of 2.1×10?4 M (S/N=3) could be obtained with an electrode temperature of 80 °C, about one magnitude lower than that at room temperature 20°. And the sensitivity was also enhanced about 10 times. |
