To build detailed models of heterogeneously catalyzed processes, surface energetics are needed to determine both thermodynamic and kinetic properties. The adsorption energy, the key property that describes the strength of the interaction between molecules and a surface, can be calculated with reasonable accuracy using density functional theory (DFT). Even though a full understanding of some systems, such as ammonia synthesis, CO oxidation, and propane dehydrogenation, has been obtained through DFT calculations on a single metal, investigating such systems on a range of metal and alloy catalysts is still much too computationally expensive. For these systems, a simple, high-throughput way of estimating binding energies is needed to screen catalysts for desirable properties.
