59. 3 support and the gold. The changes in gold dispersion were accompanied by significant changes in the metal-support interface, as inferred from the changes in the Au-O contributions; with increasing temperature treatment of flowing He, the coordination number characterizing the Au-O contribution at 2.15 Å decreased from 2.0 to 0.7, and that of the other Au-O contribution (at a distance of 2.72 Å) decreased from 1.1 to 0.2.
