Abstract

The hydrogenation of CO over a RhVO4/SiO2 catalyst has been investigated after H2 reduction at 773 K. A strong metal–oxide interaction (SMOI) induced by the decomposition of RhVO4 in H2 enhanced not only the selectivity to C2 oxygenates but also the CO conversion drastically, compared with an unpromoted Rh/SiO2 catalyst. The selectivity of the RhVO4/SiO2 catalyst was similar to those of conventional V2O5‐promoted Rh/SiO2 catalysts (V2O5–Rh/SiO2), but the CO dissociation activity (and TOF) was much higher than for V2O5–Rh/SiO2, and hence the yield of C2 oxygenates was increased.
