Pulsed laser deposition of bimetallic gold?platinum nanoparticles on cerium oxide and their characterisation by X-ray photoelectron spectroscopy and temperature-programmed desorption of isotopically labelled carbon monoxide
Original language description
Bimetallic Au?Pt nanoparticles on cerium oxide supports were prepared using pulsed laser deposition (PLD) at room temperature and investigated using X-ray photoelectron spectroscopy (XPS) and temperature-programmed desorption (TPD) of isotopically labelled carbon monoxide 13C18O. The metal deposition caused a partial reduction of Ce4+ to Ce3+. Two components in the spectra of Au (4f) and Pt (4f) photoelectrons were observed and assigned to the charged and metallic state of metals in the nanodeposits. The abundance of the charged species decreased with an increasing amount of the deposited metals and with thermal treatment of the samples. The adsorption properties of the prepared nanodeposits were examined using repeated adsorption?desorption runs of the labelled 13C18O molecules. Carbon monoxide desorbed as 13C18O with a maximum at temperatures ranging from 420 K to 500 K and as 13C16O containing 16O oxygen exchanged from the supporting oxide at temperatures from 480 to 580 K.
