Additionally, consistent with the analysis in Section 4.1, we demonstrate that accounting for mass transfer helps mitigate the overprediction of Tafel slopes, shifting the distribution towards lower values when mass transfer is explicitly handled (Figure ). It is important to note, that the size of the data set could simply be too small to observe a sharp distribution in the fit parameters due to small variabilities or errors in the experimental measurements. Collecting more data in similar conditions could potentially lead to the distribution better predicting theoretically expected values. Nonetheless, the broad distribution of parameters makes it impossible to prescribe a unique set of values that are descriptive of the CO2R on all Ag catalysts and indicate that Tafel parameters need be fitted for each individual Ag catalyst.
