In order to model the reactivity via AI, we collected candidate descriptive physical parameters characterizing the materials, reaction conditions, and potentially relevant processes governing acetylene hydrogenation. Four parameters were obtained from the experimental characterization of the materials by energy dispersive Xray analysis in a scanning electron microscope (EDX-SEM), high-resolution transmission-electron microscopy (TEM), and N 2 physisorption, such as the mean particle diameter (D µ ) and the specific surface area (s BET ).
