title: Operando XAFS study of catalytic NO reduction over Cu/CeO2: the effect of copper-ceria interaction under periodic operation.
abstract: Using an operando time-resolved XAFS technique at the Cu and Ce K-edges, we have discovered that the synchronization of Cu and Ce valence change in Cu/CeO2 under periodic (rich-lean cycling) operation can improve the catalytic activity for NO reduction at low temperature.
