D. Demri et al., C-1-OXYGENATED MOLECULES ADSORBED ON RHODIUM CONTAINING CATALYSTS - IDENTIFICATION OF A FORMYL SPECIES, Journal of molecular catalysis. A, Chemical, 104(3), 1996, pp. 237-249
The adsorption of methanol, (D-4) methanol and formaldehyde on rhodium
containing catalysts is studied by FTIR. Besides the well characteriz
ed methoxy and formate species, new bands could be observed on the CeO
2 and Pr6O11 supported catalysts. Comparison with results obtained by
chemical trapping enables us to identify the new species as a stabiliz
ed formyl. The mechanism of methanol dissociation is discussed.
