“…The results are in good agreement with the formation of two-dimensionally grown ordered PdCu 3 with Pd-Cu chains covered by Cu, as proposed earlier on the basis of LEED and STM data. 12,15 Such a conclusion is in good agreement with the fact that such a surface is only very slightly active for the 1,3-butadiene hydrogenation reaction (Table 1), a reaction for which Cu is known to be inactive but Pd is considered to be a very efficient catalyst. 16 For larger Pd deposits the Pd content at surfaces increases, but without covering the whole substrate even for quite large coverages.…”

Metal on metal deposits can have very different, and interesting, physical and chemical properties compared with those of the pure metal. In this framework we investigated the behaviour of low amounts of palladium deposited at 300 K on the (110) face of copper, but copper is known to have a lower surface energy than palladium and therefore will tend to segregate at the surface, a process that depends on the temperature.The absolute calibration of the Pd deposit was made on a polycrystalline Cu sample with the combined use of XPS and Rutherford backscattering spectroscopy: for 6 × 10 15 Pd atoms cm −2 , the intensity ratio of Pd 3d5/2 /Cu 3s is 7.2.For Pd deposited at room temperature on Cu(110), the presence of a large amount of copper at the surface is clearly evidenced by low-energy ion scattering. The Pd atomic concentration at the surface does not exceed 15% for one monolayer (ML) of Pd deposited (1 ML = 1.1 × 10 15 Pd atoms cm −2 ). This indicates either that Pd does not spray uniformly at the surface or that Cu diffusion and alloying effects do exist.These results are discussed in relation with some catalytic properties of the Pd on Cu(110) adlayers.

“…One common theme has been the interaction of metals such as platinum or palladium with copper [1,2,3] and bulk alloys of these elements [4]. We present here an investigation of the structure formed by the interaction of sub-monolayer amounts of platinum with a non-close packed surface of fcc copper; the (110).…”
