ABSTRACT: We used temperature-programmed reaction spectroscopy (TPRS) and synchrotron-radiation-based photoelectron spectroscopy (PES) to investigate the adsorption and oxidation of methanol (CH3OH) on Tb2O3(111) and TbO2(111) thin films grown on Pt(111). We find that methanol mainly desorbs from the Tb2O3 surface through both molecular and recombinative processes and that a relatively small amount of adsorbed methanol (
