英文摘要 | 循环伏安量热法研究了欠电位沉积条件下,铜在LiClO_4溶液中,铂电极上的电沉积过程,循环伏安热谱图和循环伏安微分热谱图表明,铜离子的电沉积为一放热过程.其中铜~铂(层)相互作用能为-3227.0kJ/mol.沉积铜的电氧化包括了吸热的活化和放热的氧化两个过程.活化过程的焓变为747.0kJ/mol,氧化过程的焓变为-189.9kJ/mol,与热力学数据一致.; In the present paper,cyclic voltammetric calorimetry has been used to study thedeposition of copper on platinum electrode from LiClO_4 aqueous solution. Cyclic voltammetricthermogram and cyclic voltammetric differential thermogram show that the deposition of copper on theelectrode is an exothermal process with a strong interaction between copper and platinum layer(-3227.0 kJ /mol).The electrochemical oxidation of the deposited copper is composed of twoprocesses :an endothermal activation process with 747.0 kJ/mol of activation enthalpy,and anexothermal oxidation reaction with-189.9 kJ/mol of the reaction enthalpy, which are accord withthe data from the theoritical estimation and thermodynamic handbook respectively.; 作者联系地址:沈阳医学院; Author's Address: Shenyang Medical College,Shenyang 110031University College London,London,WC1HOAJ |
