Methanol adsorption on a CeO2(111)/Cu(111) thin film model catalyst

Original language description

Presented study deals with investigation of adsorption and desorption of methanol on a CeO2(111)/Cu(111) thin film surface by XPS and soft X-ray synchrotron radiation PES. Resonance PES was used to determine the occupancy of the Ce 4f states with high sensitivity. Methanol adsorbed at 110 K formed adsorbate multilayers, which were partially desorbed at 140 K. Low temperature desorption was accompanied by formation of chemisorbed methoxy groups. Methanol strongly reduced cerium oxide by forming hydroxylgroups at first, which with increasing temperature was followed by creation of oxygen vacancies in the topmost cerium oxide layer due to water desorption. Dissociative methanol adsorption and creation of oxygen vacancies was observed as a Ce4 -Ce3 transition and an increase of the Ce 4f electronic state occupancy
