Spin adducts of methanol and ethanol electrocatalytic oxidation were detected by the spin trap method using a tiny ?2/O2 fuel cell (FC) designed for ESR in situ with a Nafion/Pt membrane electrode assembly. Spin adducts of intermediates of the direct electrooxidation of ethanol, which have not been observed earlier, were obtained by the variation of oxidation conditions, in particular, the FC potential
甲醇和乙醇电催化氧化的自旋加合物通过自旋阱方法检测,使用为 ESR 设计的微型 2/O2 燃料电池 (FC) 和 Nafion/Pt 膜电极组件。乙醇直接电氧化中间体的自旋加合物是通过氧化条件的变化,特别是 FC 电位的变化获得的。通过监测诊断曲线电位3-电流密度、功率密度3-电流密度和效率-功率密度来控制FC的工作。
