In this context, we present the Catalytic Automated Reaction Evaluator (CARE), a foundational model for heterogeneous catalysis consisting of Building the CRN in CARE proceeds in three steps, (i) the creation of a general network scheme, the CRN blueprint, composed of a list of species S and reactions R, (ii) the evaluation of the properties P, consisting of adsorbate placement and energy evaluation and (iii) the analysis of the CRN with microkinetic modeling (MKM). In a second step, the algorithm expands the CS by applying a series of bond-breaking templates generating simultaneously a set of reactions R, open-shell fragments, and unsaturated closed-shell molecules (e.g., alkenes, ketones, acids). The newly obtained species plus the CS define the extended chemical space (eCS). In contrast to homogeneous catalysis, the number of possible reaction templates in heterogeneous catalysis is relatively small but the number of events can be very large, as in polymerization/depolymerization processes involving long-chain hydrocarbons.
