Here, literature\u2010scale composition mapping and density functional theory screening are combined to identify Rh as a functional regulator of PtCo, leading to a compositionally informed synthesis of ordered Rh\u2013PtCo\/C from a Pt\/Rh mixed solution. Structural characterization supports Rh incorporation into the PtCo framework, while cluster expansion calculations predict preferential subsurface enrichment. The predicted subsurface Rh configuration downshifts the Pt d\u2010band center, moderates oxygenated\u2010intermediate binding, and strengthens the internal metal\u2013metal bonding network. Rh\u2013PtCo\/C consequently delivers a mass activity of 1.792\u00a0A mg\n                    <jats:sub>Pt<\/jats:sub>\n                    <jats:sup>\u22121<\/jats:sup>\n                    and a total\u2010PGM\u2010normalized activity of 1.59\u00a0A mg\n                    <jats:sub>PGM<\/jats:sub>\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 0.9\u00a0V versus RHE.
