研究了微量一氧化碳在Pt/C催化剂上和在硫酸电解液中电氧化反应动力学.在0.947V下,其经验速率方程如下,其中y为一与H_3O~+浓度有关的参数. i=k_αP_(co)C_(H_3~+O)~yexp(-E_α/RT) 假设反应的速率控制步骤为吸附的CO和吸附的OH间的电化学反应,则可导得与经验速率方程具有相同形式的理论速率方程.
The kinetics of the electrooxidation of trace amounts of carbon monoxide on Pt / C catalysts and in sulfuric acid electrolytes was studied. The empirical velocity equation at 0.947 V is as follows, where y is a parameter related to H 3 O + concentration i = k_αP_ (H_3 ~ + O) ~ yexp (-E_α / RT) Assuming that the rate-controlling step of the reaction is the electrochemical reaction between the adsorbed CO and the adsorbed OH, the theory of the same form as the empirical rate equation can be derived Rate equation.
