Figure 3: Charge-state-dependent electrochemical HER mechanisms catalysed by PtAu24.
From: A molecule-like PtAu24(SC6H13)18 nanocluster as an electrocatalyst for hydrogen production
Dependence of the catalytic current, Ic, (a) on the concentration of TFA in the presence of PtAu24 (1 mM) and (b) on the concentration of PtAu24 in TFA (1.0 M) solution at −1.3 (blue), −1.8 (green) and −2.2 V (purple). Insets show plots for dependence of the Ic on the concentration of (a) TFA and (b) PtAu24 at −1.0 V. The data are fitted by first-order linear functions (solid lines).
