Abstract
The spatial distribution of the two components at the surface of small RhM/Al2O3 (M=Sn, Pb, Ge) bimetallic aggregates has been investigated by using hydrogenolysis of model alkanes, IR spectroscopy of adsorbed CO and quantum chemical calculations. The addition to a Rh aggregate of a small amount of Sn or Pb inhibits selectively the sites of low coordination, and this demonstrates that there is a topological segregation to these sites; Ge atoms appear to be randomly distributed at the surface. Quantum chemical calculations of the relative stabilities of Rh12M model clusters support these conclusions.
