ملخص: The adsorption of methanol, (D4) methanol and formaldehyde on rhodium containing catalysts is studied by FTIR. Besides the well characterized methoxy and formate species, new bands could be observed on the CeO2 and Pr6O11 supported catalysts. Comparison with results obtained by chemical trapping enables us to identify the new species as a stabilized formyl. The mechanism of methanol dissociation is discussed.
