    • Because of the noise in the low-Z backscatterer region, the EXAFS data provide only limited evidence of possible Au-C shells in the samples containing gold clusters from which the ligands had not been fully removed. For example, the sample treated in He at 323 K was characterized by a small Au-C shell with a coordination number of 0.5 at a distance of 1.80 Å, indicating remaining carbonaceous species, but it was not possible to fit any Au-C shells for other samples treated at temperatures below 573 K, although the IR spectra indicate the presence of organic ligands.

    • 27,28 the former results indicating stable three-dimensional nanoclusters of more than 4 gold atoms but the latter indicating two-dimensional nanoclusters of as many as 6 or 7 atoms (unless geometrical constraints are imposed, in which case stable octahedral structures of 6 atoms can be obtained). In view of the inconsistency of these results and the lack of theoretical investigations of the effects of supports on gold nanoclusters, an incisive comparison of our results with theoretical results awaits further work.
