Tuning the Metal-Adsorbate Chemical Bond through the Ligand Effect on Platinum Subsurface Alloys

Scratching beneath the surface: Pt‐M3d‐Pt(111) (M3d=Co, Ni) bimetallic subsurface alloys have been designed to show the ligand effect tunes reactivity in oxygen and hydrogen adsorption systems. The platinum–oxygen bond order was investigated by oxygen atom projection in the occupied and unoccupied s...

Description
Summary:Scratching beneath the surface: Pt‐M3d‐Pt(111) (M3d=Co, Ni) bimetallic subsurface alloys have been designed to show the ligand effect tunes reactivity in oxygen and hydrogen adsorption systems. The platinum–oxygen bond order was investigated by oxygen atom projection in the occupied and unoccupied space using X‐ray emission spectroscopy (XES) and X‐ray absorption spectroscopy (XAS).
