Moreover, note that in this study we do not include additional partial pressure of hydrogen, in order to closely mimic surface science experiments on model catalysts, where the partial pressure is negligible. These settings are also relevant to applications in endothermic cooling in aviation. While hydrogen gas is added in industrial dehydrogenation to slow down coking, our goal is to instead prevent coking through alloying. This serves as an additional motivation for our model. Added hydrogen coverage might shift but should preserve the found trends.
