Scientists from Japan have discovered that the synchronization of Cu and Ce valence charge in Cu/CeO2 catalysts can improve the catalytic activity for NO reduction. They used an operando time-resolved XAFS technique at the Cu and Ce k-edges to study the catalytic NO reduction under periodic (rich-lean cycling) operation.
