V. Ponec, ON THE ROLE OF PROMOTERS IN HYDROGENATIONS ON METALS - ALPHA,BETA-UNSATURATED ALDEHYDES AND KETONES, Applied catalysis. A, General, 149(1), 1997, pp. 27-48
Promoters of metal catalysts play an essential role in the hydrogenati
on of unsaturated bonds, such as in carbonylic compounds. This promoti
on is a key to a high selectivity to unsaturated alcohols in hydrogena
tion of alpha,beta-unsaturated aldehydes. Analysis of the information
available in the Literature on the adsorptions through the C=C and C=O
groups, respectively, together with the information on the catalytic
behaviour of the promoter-free and promoted catalysts, allows us to su
ggest a model of surfaces active in selective hydrogenation of unsatur
ated aldehydes.
