On the kinetics of CO oxidation by O2 over RhI(CO)2 catalytic species anchored to a zeolitic support

Résumé

The reactivity of RhI(CO)2 towards CO oxidation was studied on a model Rh(0.7 wt%)/HY material. The kinetic results show that RhI(CO)2 exhibit a fairly low activity. It is therefore suggested that the catalytic species responsible for the enhanced activity of Rh/Ce0.68Zr0.32O2 [Manuel et al., J. Catal. 224 (2004) 269] would rather be electron-deficient Rh clusters (Rhnδ+).
