Methanol Adsorption and Decomposition on Pt/CeO2(111)/Cu(111) Thin Film Model Catalyst

Research on fuel cells has expanded and a promising material for direct methanol fuel cells is platinum loaded ceria (cerium oxide). The interaction of methanol with Pt nanoparticles and roughened Pt crystals has been investigated.

            Currently there is intense interest in wide range of energy technologies, from solar energy to battery technology to energy storage science. Research on fuel cells has expanded and a promising material for direct methanol fuel cells is platinum loaded ceria (cerium oxide). For this reason the interaction of methanol with Pt nanoparticles and roughened Pt crystals has been investigated.Resonant Photoemission Spectroscopy (ResPES) was used to determine the occupancy of the Ce 4fstates with high sensitivity: upon reduction Ce can change its oxidation state in the oxide from IV to III, and ResPES is a sensitive method for observing this change.  

The Materials Science Beamline is well adapted to these measurements and to the photoelectron spectroscopy of the Pt 4f core level.
