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。 The potentiodynamic step coulometry coulometric method was used to determine the amount of electricity needed to oxidize the adsorbed intermediates and dissolved intermediates during oxygen reduction at different electrode potentials. Experiments show that during the process, There are indeed adsorption intermediates exist, but also a function of the electrode potential, but its molecular properties still need further identification.
