2.47 Å in bulk Ni), and the low coordination number of the second coordination shell (Figure , Table ). CO-adsorption IR spectroscopy revealed that the Pd and Pt materials are reduced after the hydrogen treatment, and no bands corresponding to CO bound to oxidized sites were observed. The reduction of 1-Pd/SiO2-700 was further investigated by in situ XAS-TPR which revealed that a large proportion of Pd is readily reduced in H2 at room temperature (Figure ). However, the final temperature is required to remove all ligand residues from the surface.
