Fig. 5: Understanding cation identity effects.
From: Disentangling the Janus-faced effects of cations in electrocatalysis
a Simulated and b experimental polarizations curves for HER on Au in 0.1 M KOH, NaOH, and LiOH, with experimental data taken from ref.7. Calculated electric field strength within the OHL for c K⁺ and d Li⁺. e Influence of cation adsorption on the Tafel slopes. The results without considering cation adsorption are shown for comparison. f Schematic illustration of the underlying mechanisms for the inversion of cation identity-dependent activity. The results are simulated using Eqs. 3–8 and parameters in Table 1. Source data are provided as a Source Data file.
