Nanoscale bimetallic catalysts: are they really bimetallic?

L. Guczi, Dominique C. Bazin, Z. Schay, Imre Kovács

Abstract

Abstract The existence of bimetallic particles (and their reducibility and location on/or in the support) in Ru–Co/NaY and Pt–Co/NaY samples has been studied by in situ X‐ray adsorption spectroscopy (XAS). It is established that in Ru–Co/NaY the monometallic clusters maintain their identity, whereas in Pt–Co/NaY the existence of small bimetallic particles can be established. In both cases the results are supported by other techniques, such as XPS and temperature‐programmed reduction. Copyright © 2002 John Wiley & Sons, Ltd.
