Results from experimental studies and theoretical calculations indicate that selective C-O hydrogenolysis over Re-promoted Rh/C occurs through acid catalysis, initiated by hydroxyl groups associated with rhenium and rhodium, providing a consistent account for the nature of the active site in metal catalysts promoted with oxophilic additives for hydrogenolysis reactions.
