Nuclear magnetic resonance study of the Pt-Rh bimetallic clusters
We report the study of supported Pt-Rh bimetallic catalysts by 195Pt NMR and by 13C NMR of adsorbed CO. The metal particles are sA-soA in diameter. Study of the dependence of the 13CO resonance position as a function of Pt/Rh ratio and particle size shows that Rh is segregated to the surface. Study …
