• 中文摘要： 本文主要研究鹼性KOH溶液中苯甲醇在鎳電極上之電催化氧化,以循環狀安及極化曲線法來研究苯甲醇在電極上之氧化機構。由衍導之動力方程式及實驗結果之比較可得反應動力式及其參數,這些參數係以由不同濃度之極化曲線及動力模式獲得,所得動力模式中之參數為 K/sub 1/(E)=4.89*10/sup -7/exp(FE/RT)mol/sup -1/dm/sup 3/及k/sub 3//sup (1/2)/K/sub 2/=2.22*10/sup -5/dm/sup (3/2)/ mol/sup (-1/2)/s/sup (-1/2)/,其中E表示相對Ag/ AgCl參考電極之電位。
• 英文摘要： The electrocatalytic oxidation of benzyl alcohol was investigated on a nickel electrode in 1M KOH. The mechanisms of benzyl alcohol oxidation on the electrode were studied via cyclic voltammetry and polarization curves. The kinetic equations were derived and the kinetic parameters were obtained from a comparison of experimental results and the kinetic equations. These rate constants were determined from the current-potential curves and the kinetic model at various concentrations of benzyl alcohol. The kinetic parameters in the proposed kinetic model could be expressed as K/sub 1/(E)=4 .89*10/sup -7/exp(FE/RT)mol/sup -1/ dm/sup 3/, k/sub 3//sup (1/2)/K/sub 2/=2.22*10/sup -5/ dm/sup (3/2)/mol/sup (-1/2)/s/sup (-1/2)/, where E was the applied potential vs. Ag/AgCl.
