摘要：
NO adsorption at Room Temperature on Fe-ZSM-5 leads to the formation of several intermediates: Fe(n+)(NO) (n = 2, 3) species, Fe(2+)(NO)(m) (m = 2, 3) complexes, Fe-(NO(2)) and NO(+), with complex equilibria and different stabilities. In this work the mechanisms of nitrogen oxides formation (NOx) on Fe-ZSM-5 prepared by iron (III) oxalate method are examined, principally by means of FTIR, and the existence of an active site for N(2)O decomposition containing both Fe and Al is proposed.
