The Preparation and Characterization of a Model Supported Ruthenium Catalyst

A model supported Ru catalyst was prepared by sputter depositing the metal onto a thin alumina film that had been formed by anodic oxidation of Al foil. The metal loading could be varied by changing the time of sputtering, and in this way the growth of the metal was investigated with XPS. Static SIM...

Zusammenfassung:A model supported Ru catalyst was prepared by sputter depositing the metal onto a thin alumina film that had been formed by anodic oxidation of Al foil. The metal loading could be varied by changing the time of sputtering, and in this way the growth of the metal was investigated with XPS. Static SIMS combined with temperature-programmed desorption (TPD) was used to study carbon monoxide adsorption and to evaluate the metal--gas bonding, and the metal--oxide interaction.
