Formation of C2 oxygenates on rhodium-containing catalysts during CO + H2 reactions. FTIR study of acetaldehyde adsorption

The adsorption of acetaldehyde on promoted and unpromoted Rh/Sio2 catalysts has been studied. The use of labelled compounds and the adsorption of acetic acid and crotonaldehyde allowed the unambiguous identification of an acetyl species on the promoted catalysts. The mechanism of C2-oxygenate formation and the role of the promoters are discussed.
