氧还原金属催化剂的塔菲尔曲线测定?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 e ... j是直接测试得到的电流,jd可以借助旋转圆盘电极得到。总之,Tafel是纯动力学的研究,因此其电流必须为动力学电流。j是由动力学因素和扩散因素共同影响的,这个方程就是从j中减去mass-transfer影响(jd),从而得到纯动力学电流密度。查看更多
