In this study, we aim to improve the adsorption predictions from ICOHP values by expanding our analysis beyond the active site by including contributions from neighboring and nextneighboring sites for our extended metal-oxide dataset. We analyze the relationship between the COHP and the adsorption energies through size extrapolation. Furthermore, we perform a direct comparison of COHP values between series of isoelectronic systems and impact on their COHP. Finally, we discuss possible strategies to resolve some discrepancies in the ICOHP descriptor.
