14. 2 remaining in the feed, EXAFS spectra again showed the formation mononuclear gold complexes bonded to approximately two O atoms of the support.
15. Although the presence of gold carbonyls and formates is indicated by the IR spectra, the EXAFS data were not sufficient to demonstrate their presence (it was not possible to fit any Au-C contributions in the EXAFS spectra).
