摘　　要：考察了中性分子电对Ｈ_２Ｑ／Ｑ在１３Ｘ型分子筛修饰电极上的电化学行为。发现Ｈ_２Ｑ／Ｑ电对在修饰电极上电响应迅速，为双电子可逆反应，不受溶液温度及电极与溶液相对运动的影响，而与溶液的ｐＨ值有关。当ｐＨ≤２．０时，修饰电极对Ｈ_２Ｑ／Ｑ电对的氧化／还原有明显的催化作用．A procedure was described where an 13X-type zeolite film could be formed on a glassy carbon electrode. Using cyclic voltammetry, we surveyed the electroresponses of H2Q/Q redox couple at the modified electrode thus formed. The stable cyclic voltammograms were obtained rapidly, and were not altered when the temperature of the solutions was changed or the solutions were stirred, but they were effected by the solutions'pH values. It was observed that both the oxidation of H2Q and the reduction of Q were catalyzed by the modified electrode when pH≤2.0.
