Methanol Adsorption and Decomposition on Pt/CeO2(111)/Cu(111) Thin Film Model Catalyst
Original language description
Adsorption and desorption of methanol on Pt particles on a CeO2(111)/Cu(111) thin film surface and on an ion-eroded Pt(111) single crystal were investigated by X-ray photoelectron spectroscopy and soft X-ray synchrotron radiation photoelectron spectroscopy (PES). Resonant PES was used to determine the occupancy of the Ce 4f states with high sensitivity. Multilayers of methanol were adsorbed at low temperature and subsequently desorbed by heating to 600 K. Methanol desorption is accompanied by the formation of chemisorbed methoxy -OCH3. Cerium oxide surface is strongly reduced by methanol, which was detected via the transition Ce4+ -} Ce3+ and an increase of the Ce 4f electronic state occupancy. Partial C-O bond scission and formation of atomic carbon was observed on the Pt particles as well as on the rough Pt(111) surface. On Pt/CeO2(111), all traces of surface carbon and residual hydrocarbons disappear at 500 K.
