Steam and CO2 reforming of ethanol over Rh/CeO2 catalyst

▶ Rh/CeO2 high surface area catalyst exhibited better stability in SR of ethanol, with no carbon formation. ▶ DRIFTS experiments revealed that Rh carbonyl bands were quite s, showing no carbon deposits. ▶ Improved stability is likely attributed to a greater fugacity of available O from the support. ▶ O adatoms or surface OH groups from the support takes part on the carbon removal mechanism.
