XAS of electronic state correlations during the reduction of the bimetallic PtRe/Al2O3 system.

Many bimetallic systems are easy to study due to differences in the backscattering function of the two elements but this is not the case for a system like the PtRe bimetallic system (D. BAZIN et al. 1997). For this catalyst, the proximity of the L edges of the metals as well as their similar backscattering amplitude and phase constitutes a major l imitation. Here, we describe a new approach using the proximity of the L edges of the metals in order to follow "simultaneously" the evolution of their electronic states during reduction.
