To establish an improved catalytic descriptor incorporating nonlocal bonding environments to accurately predict oxidative adsorption and catalytic activity across transition-metal oxides.
Expanded the Integrated Crystal Orbital Hamilton Population (ICOHP) framework beyond the active site using bond-decomposed analysis to incorporate nonlocal adsorption effects.
Evaluated the size-extrapolated ICOHP descriptor across diverse transition-metal oxide systems, including 3d, 4d, 5d, and d0 electronic configurations.
Extrapolated size changes in ICOHP demonstrated strong linear correlation with adsorption energies, achieving slopes near unity for 4d and 5d metals and roughly half that for 3d metals.
Identified that adsorption-induced shifts in magnetic moments and uncaptured nonbonding traits in 3d high-spin metals account for differences in descriptor scaling.
Successfully predicted adsorption properties across all systems, including previously excluded d0 metal oxides.
