Abstract

A comprehensive mechanism is provided for surface transformations in the H3Re3(CO)12/Al2O3 and NH4ReO4/Al2O3 induced by treatment in vacuo, hydrogen and CO + H2 mixtures. Both inorganic and organometallic precursors are partly transformed to the same, rather stable Re4+ species during pretreatment. Regardless of the nature of the starting materials, a common intermediate species, Re(CO)3(OAl)(HOAl)2, is shown to be formed under the reaction conditions employed, provided that the Re0 or Re4+ species produced possess ultra-high dispersion.
