Systematic process exploration for such a complex system as done here has therefore only become tractable through the massive efficiency gain brought about by the use of a MLIP DFT-surrogate. The surprisingly large number of identified inequivalent processes immediately hints at a level of complexity that stands in stark contrast to prevalent microkinetic models in surface catalysis that typically comprise only 1-2 dozen hand-selected elementary processes. It is not the sheer number that matters, however, but the fraction of low-barrier processes and their corresponding complexity. In other words, are they intuitive enough that a human researcher with sufficient domain knowledge would have considered them, too? With collective motion of multiple atoms typically associated with a certain degree of non-intuitive complexity, we therefore proceed to analyze the number of significantly displaced atoms in each elementary process, using a cutoff of 0.5 Å. Figure summarizes the results, additionally showing the distribution of barriers associated to the processes. As an important marker we thereby employ 1.0 eV. With reported apparent activation barriers of CO or methane oxidation somewhere around or above, we use this value as a rough threshold to identify low-barrier processes that happen on comparable time scales than those of the catalytic processes.
