CeO2-x is capable of catalyzing the reaction of HCl and O2 to form Cl2 and H2O, a process which is of great industrial interest. Amrute et al. published a DFT based catalytic cycle for the HCl oxidation over CeO2(111) together with FTIR measurements of nano particle CeO2 powders [1]. In this contribution we provide first surface science experiments, in combination with DFT modeling and calculations, for the HCl oxidation on crystalline CeO2-x(111) films with 1.5
