氧还原金属催化剂的塔菲尔曲线测定？确实是用RDE得到的以上数据。横坐标其实是 动力学电流密度的对数， 也就是jK；它用K-L方程转换了一下！纵坐标是电压。??最主要是说明 低过电势条件下和高过电势条件下??Tafel斜率是不一样的。 文献上是这么说的“The Tafel plots were obtained after the measured currents were corrected for diffusion to give the kinetic currents in the mixed activation–diffusion region, calculated from the equation: j k = [j/(jd-j)], where j is the overall measured current density, j k is the kinetic current density, j d is the boundary-layer diffusion-limited current density and [j/(jd-j)] is the mass-transfer correction。”??请问这里的j和jd是怎么测得的？用K-L方程怎么转换呢，查看更多
