A novel catalytic role for transition‐metal cations in the homogeneous conversion of the nitrogen oxides NO 2 , NO, or N 2 O and CO into N 2 and CO 2 is demonstrated by thermodynamic and kinetic studies of gas‐phase reactions of 29 transition‐metal cations and some of their oxides (see scheme). Fe + , Os + , and Ir + ions are shown to be most effective. The chemistry identified may have practical applications in new designs of catalytic converters.
