Atomic diffusion pathway mediated subsurface engineering.

ABSTRACT: Subsurface regions critically govern surface events, such as the interactions with reactants in heterogeneous catalysis, thereby significantly modulating catalytic performance. However, precise control of subsurface atomic arrangement remains challenging due to complex metal-adsorbate interactions and limited structural accessibility. Here we achieve precise control of subsurface atomic layer in platinum-based intermetallic compounds through targeted positioning of heterometallic atoms to subsurface via in-situ constructed atomic diffusion pathways. This site-specific placement and subsequent thermodynamic-induced atomic rearrangement are governed by surface energy minimization and adsorbate-induced segregation. Through atomic-precision subsurface engineering, we successfully synthesize a
