Formation of N3(-) during interaction of NO with reduced ceria

Chem Commun (Camb). 2015 Apr 4;51(26):5668-71. doi: 10.1039/c5cc00500k.

Abstract

We show that the first stages of interaction between NO and reduced ceria comprise the formation of azides, N3(-), with simultaneous oxidation of Ce(3+) to Ce(4+). This finding imposes revision on some current views of catalytic NO conversion and may contribute to design of new deNOx materials and processes.
