Metal binding energy

By XPS spectra, Endo et al. [96] confirmed that formation of binary structure prevented Pd atoms from oxidation in the AuPd and PtPd bimetallic nanoparticles which exhibited higher catal5hic activity than monometallic ones. Wang et al. [112]. characterized PtCu bimetallic alloy nanoparticles Ijy XPS. XPS revealed that both elements in the nanoparticles are in zero-valence and possess the characteristic metallic binding energy.

Fig. 6. AS, the difference between free atom and metallic binding energies of 2s or 2p core levels in the elements Ti through Zn. Estimates by Ley et al. [Ref. (79)], shown as filled circles, are based on dnsm configurations which were taken to differ between atom and metal for all elements except Cr and Zn. The open circles are values based on free atom binding energies for atom configurations d s most closely corresponding to the metallic d electron counts. (See text.)...

The heat of solution of II in a uniform electron gas has a minimum at an electron density of 0.002 e/(Bohr radius)3, with A/-, un fo"n given by —1.7 eV, in just the range of chemisorption energy found in fig. 17. Al a surface, the picture is then that the H atom seeks out the optimum electron density, giving this rather universal (for s-p metals) binding energy.
