EXAFS Studies of the Behavior of Rh6(CO)16 Supported on γ-Al2O3 Surface

Abstract
The structural change of Rh6(CO)16 supported on γ-Al2O3 surface during a decarbonylation–recarbonylation cycle was studied by means of EXAFS (extended X-ray absorption fine structure) spectroscopy. Rh6(CO)16 cluster framework was found to be decomposed into Rh(CO)2(OAl(Remark: Graphics omitted.))2 after the reaction with a mixture of O2 and H2O, and reversely regenerated by the subsequent treatment with a mixture of CO and H2O.
