P. Gronchi et al., ON THE FORMATION OF OXYGENATED PRODUCTS BY CO HYDROGENATION WITH LANTHANA PROMOTED RHODIUM CATALYSTS, Reaction kinetics and catalysis letters, 60(1), 1997, pp. 79-88
La2O3 with Rh based catalysts, has a promoting effect on the carbon ef
ficiencies of C1 and C2 oxygenated products. CO2 seems specifically in
volved in the reaction pathway. Its formation and activation may indee
d lead to stabilized undissociated CO (stabilized acyl group) which ev
olves further to oxygenated products (ethanol).
