Atomic-Scale Assembly of a Heterogeneous Catalytic Site

The (100) surface of a AuPd bulk alloy was imaged by scanning tunneling microscopy. Chemical-contrast revealed structures with short-range order involving surface Pd atoms at c(2x2) sites with respect to the surface lattice—a first time observation of a known active heterogeneous catalytic site with atomic resolution. Comparison of the Pd distribution in a AuPd(100) surface with that in a Au3Pd(100) surface shows the unique thermodynamic properties of the 50 : 50 alloy are decisive in controlling the formation of isolated Pd sites.
