Figure 4. Multi-adsorbate thermodynamic filtration and compositional convergence. (A) *OCH₂CH₃-*CO adsorption-energy landscape with *H adsorption-energy coding and the target adsorption-energy window marked by solid lines; (B) Overlap and UpSet analysis of structures satisfying the individual *OCH₂CH₃, *CO, and *H adsorption-energy criteria; (C) Contraction of adsorption-energy distributions before and after multi-adsorbate filtering; (D) Element-level enrichment of positive structures relative to the full structure set, expressed as lift; (E) Unary, binary, ternary, and quaternary fractions before and after screening.
