Ru(NO)(NO3)(3)/SiO2 catalyst precursors were characterized via XPS and in-situ reflectance IR spectroscopy before, during and after reduction by hydrogen over the temperature range 300-800 K. IR results indicated that the catalyst precursor lost NO3 groups first, with subsequent loss of NO both in a reducing atmosphere and during thermal annealing. XPS was used to derive information on the oxidation state of Ru in the various steps of the annealing and/or reduction processes. (C) 1997 Elsevier Science B.V.
