Rapid phase fluxionality as the determining factor in activity and selectivity of highly dispersed, Rh/Al2O3 in deNO(x) catalysis
Rapid phase fluxionality as the determining factor in activity and selectivity of highly dispersed, Rh/Al2O3 in deNO(x) catalysis
The nature of oxide-supported metal catalysts may change in oxidising conditions: Studies on the correlation between the Rh phase in the structure of the Rh/AL2O3 catalyst and the catalytic performance for the reduction of NO by H2 to N2 (on reduced, metallic sites) and N2O (on oxidised sites) reveal that the phases of the supported metal species can be interconverted on time scales that can be deterministic in temrs of the activity and selectivity of the catalysts.

Abstract
The nature of oxide-supported metal catalysts may change in oxidising conditions: Studies on the correlation between the Rh phase in the structure of the Rh/AL2O3 catalyst and the catalytic performance for the reduction of NO by H2 to N2 (on reduced, metallic sites) and N2O (on oxidised sites) reveal that the phases of the supported metal species can be interconverted on time scales that can be deterministic in temrs of the activity and selectivity of the catalysts.
