摘要: 应用改进了的旋转全电极上的电势阶跃计时库仑法,分别测定了不同电极电势下氧还原过程中电极吸附中间物和溶解中间物氧化所需的电量,实验证明,在此过程中电极上确有吸附中间物存在,而且是电极电势的函数,但其分子属性尚需进一步鉴别。

Abstract: Applying the ameliorated PSCC on RDE, the electric quantities needed for the soluble and adsorbed intermediates during the reduction process of oxygen on Au electrode in alkaline solution were measured, respectively. The results demonstrate that the quantity of adsorbed intermediate is dependent on the electrode potential. However, its molecular specificity is still required to be identified.
