All considered, the existence of an apparent correlation likely suggests that, among other factors, the poor quality of experimental data in CO2R leads to apparent compensation effects that contribute to the broad distribution of the fitted parameters observed in Section 4.2. Future work should use more sophisticated objective functions that weight data points according to their associated uncertainty, but the underlying issue is that many reports in CO2R do not report polarization data with defined error bars. Additionally, reporting electrochemical data with respect to ECSA or using less-complex electrodes would also improve data quality for model fitting. Indeed, the poor quality of experimental data in electrocatalysis and the need for more easily interpretable electrocatalytic measurements has been well-documented in recent work. The analysis presented here further underscores the need for better standards and protocols for acquisition of experimental data that can then be used to validate results obtained by theoreticians.
