Molecular modelling of supported metal catalysts: SiO 2 -grafted [{(η 3 -C 4 H 7 ) 2 Rh} 2 V 4 O 12 ] and [{Rh(C 2 Me 5 )} 4 V 6 O 19 ] are catalytically active in the selective oxidation of propene to acetone

SiO2-grafted [{η3-C4H7)2Rh}2 V4O12] and [{Rh(C2Me5)}4V6O19], as molecular models of supported Rh catalysts characterized by EXAFS, FTIR and TPD studies, exhibit high catalytic activities for the selective oxidation of propene to Acctone.
