The adsorption of NO molecules on Mndoped CeO2 (111) surfaces for NO oxidation has been studied by employing the periodic density functional theory plus U (DFT+U) method. Through our calculations, it is demonstrated how Mndoped CeO2 with superior NO oxidation activity benefits from the high mobility of the oxygen near the Mn cations. On unreduced Mndoped CeO2 (111) surfaces, the NO molecule ...
