説明
Abstract The formation of hydrocarbons in the reactions of CO + H2 and CO2 + H2 was studied over rhodium catalysts supported on Nb2O2, ZrO2, Al2O3, SiO2 and MgO. Among these catalysts, Rh on Nb2O5 was most active in the reaction of CO + H2 and RhMgO was least active. In the hydrogenation of CO2, RhZrO2 was more reactive than RhNb2O5 and showed measurable activity even at 50°C, in contrast to the inactivity at temperatures up to 130°C in the CO + H2 reaction. The inverse kinetic isotope effect was observed in both reactions of Co + H2(D2) and CO2 + H2(D2) over RhNb2−O5 and RhZrO2. However, the isotope effect was not observed in the CO2 reaction over RhAl2O3, whose effect in the CO reaction was still inverse. The mechanisms of the above reactions are correlated to the IR study of the adsorbed species.
