Abstract

We show that the first stages of interaction between NO and reduced ceria comprise the formation of azides, N₃⁻, with simultaneous oxidation of Ce³⁺ to Ce⁴⁺. This finding imposes revision on some current views of catalytic NO conversion and may contribute to design of new deNO_x materials and processes.
