Abstract

Temp.-programmed redn. (TPR) and Moessbauer expts. on FeRh/SiO2 catalysts show clear evidence for the formation of bimetallic particles. The degree of redn. in FeRh/SiO2 is substantially higher than in Fe/SiO2 catalysts, proving that Rh acts as a catalyst for the redn. of Fe. Oxidn. of reduced FeRh/SiO2 at room temp. mainly causes oxidn. of Fe while Rh remains in the metallic state. This is probably due to the fact that the bimetallic FeRh particles consist of an outer shell enriched in Fe, while the core contains most of the Rh. [on SciFinder (R)]
