Je. Bailie et al., IR STUDY OF ACROLEIN HYDROGENATION OVER CO SIO2 CATALYSTS/, Journal of the Chemical Society. Faraday transactions, 93(24), 1997, pp. 4389-4394
Gas-phase and surface spectra are reported for Co/SiO2 exposed at 295
and 373 K, with and without hydrogen, to acrolein, propanal, allyl alc
ohol and propan-1-ol. Adsorbed species on silica, Co degrees and oxidi
sed Co sites with accompanying oxide ions are discussed in relation to
the hydrogenation reactions of acrolein. The dominant reaction involv
ed propan-1-ol formation via propanal. Providing that Co degrees sites
were present to dissociate hydrogen, hydrogenation of alkenyl groups
in adsorbed species on silica or oxidised cobalt sites readily occurre
d but did not necessarily constitute a mechanism for product formation
.
