Experimental procedures that capture the kinetics of the formation of the active phase from the catalyst precursors have been designed and specified in a SOP. 5 A typical set of twelve chemically and structurally diverse catalyst materials was included in the study that combines rigorously conducted clean experiments in catalyst synthesis, physicochemical characterization and kinetic evaluation with interpretable AI using the sure-independence-screening-and-sparsifying-operator (SISSO) symbolicregression approach. 9 Previously obtained empirical findings are correctly reflected by the data analysis, which proves the value of the data set.
