应用统计力学方法建立的电极过程速度方程,在假定氢析出反应遵循催化机理的前提下,提出吸附氢原子间排斥能估算方案,计算了Ni、Pt、Pd、Cu、Ag、Au等六种面心立方金属电极上氢析出反应～lgi曲线,结果表明,其Tafel斜率b决定于电极表面吸附氢原子间的相互排斥作用,而截距a刚和金属原子半径、晶面点阵排列以及氢的吸附热等因素有关。 The velocity equation of the electrode process established by statistical mechanics method is proposed, and on the premise of the hydrogen evolution reaction follows the catalytic mechanism, an estimation scheme of the repulsive energy between adsorbed hydrogen atoms is proposed. Six kinds of Ni, Pt, Pd, Cu, Ag and Au The results show that the slope of Tafel b is determined by the mutual repulsion between the hydrogen atoms adsorbed on the electrode surface, and the intercept a is just as small as the radius of the metal atom, lattice lattice arrangement and hydrogen Adsorption heat and other factors.
