Title: Structure-Sensitive Scaling Relations: Adsorption Energies from Surface Site Stability

Abstract

Here, the design of heterogeneous catalysts is accelerated by the identification of thermochemical reactivity descriptors, which enable the prediction of promising materials through efficient screening. Motivated by previous discoveries of linear scaling relations between the adsorption energies of related atoms and molecules, we present a new scaling between the adsorption energies of metal atoms and metal–adsorbate complexes, which can be used to directly predict catalytically relevant molecular adsorption energies. In contrast to existing models based on the coordination number of surface atoms alone, our model can predict adsorption energies with site–by–site resolution considering local structural effects and also has potential extensions to include contributions of neighboring metal identity in alloy systems. Integration of this scaling with a previously identified model for metal–metal interactions enables the accurate prediction of molecular adsorption energies on nanoparticles by performing only a small set of slab–based calculations.
