Abstract
Abstract New perspectives derive from classical transition state theory applied to hydrogen evolution reactions (HER). Trasatti found exchange current density j 0 increases exponentially with metal electrode work function Φ. Elementary electron transfer step M(e)+H + ads ⇄M(0)+H • ads specifies metal in the transition state to derive rate equations where metal-specific physiochemical property Φ is explicit. Linearity of log j 0 with Φ is quantified. Φ raises j 0 because Φ lowers activation energy. Material specific properties in rate expressions provide opportunities for a priori electrocatalyst design and fundamental insights on electron transfer. New perspectives derive from revisit of established HER data with classical transition state theory.
