摘要：

A newly designed high-pressure infrared cell reactor has been used to study the reactions of CO and CO2 with H2 over Pd/La2O3 films. The activation energy for the CO2 hydrogenation (25.1 kcal mol-1) to produce methanol is higher than that reported elsewhere for the analogous CO hydrogenation reaction. It is proposed that the CO2 reaction proceeds through hydrogenation of adsorbed CO, rather than by direct hydrogenation of CO2 over Pd/La2O3. © 1990.
