It is important to note that adjusting species' enthalpies using linear scaling relationships can alter reaction enthalpies, necessitating the recalculation of transition states to ensure realistic reaction rates. As a substitute for DFT, and to reduce computational costs, the Brønsted-Evans-Polanyi (BEP) relationship, a linear relationship between the reaction enthalpy and activation energy, is commonly employed in published works. As discussed by Abild-Pedersen et al., a preliminary catalyst screening can be done by acquiring an estimate of the full energy diagram of surface reactions on a range of catalysts with linear scaling and BEP relations. This could be followed by DFT calculations or experiments on any promising catalyst found in the screening.
