The CO hydrogenation reaction over the Rh(111) and (211) surfaces has been studied operando using X-ray photoelectron spectroscopy at a pressure of 150 mbar. Observations of the resting state of the catalyst provide mechanistic insight into the selectivity of Rh for ethanol generation from CO hydrogenation. The study shows that the Rh(111) surface does not dissociate all CO molecules before hydrogenation of the O and C atoms, resulting in the visibility of methoxy and other oxygenated and hydrogenated species in the photoelectron spectra.
The CO hydrogenation reaction over the Rh(111) and (211) surfaces has been investigated operando by X-ray photoelectron spectroscopy at a pressure of 150 mbar. Observations of the resting state of the catalyst give mechanistic insight into the selectivity of Rh for generating ethanol from CO hydrogenation. This study shows that the Rh(111) surface does not dissociate all CO molecules before hydrogenation of the O and C atoms, which allows methoxy and other both oxygenated and hydrogenated species to be visible in the photoelectron spectra.
