摘要
采用循环伏安法和计时电流法研究了丙酮浓度和反应温度对Pd电极上异丙醇直接电氧化的影响.研究发现,丙酮对Pd电极上异丙醇电氧化存在严重的毒化作用,并提出了其发生竞争吸附的毒化作用机理.
The effects of acetone concentration and reaction temperature on the electrooxidation of 2-propanol at Pd electrode were investigated by cyclic voltammetry and chronoamperometry.The results show that acetone significantly poisons the electrocatalytic activity of Pd for 2-propanol oxidation.A competitive adsorption mechanism was proposed to interpret the poisoning effect.
