摘要: Catalytic properties of the zeolite H-ZSM-5 doped with iron have been studied. The atomic activity of Fe in the zeolite is proved to be higher by several orders of magnitude than its activity in Fe 2 O 3. The decomposition of N 2 O at low temperatures (below 300° C) occurs in an unusual way, being accompanied by oxygen binding at the surface. There is one active site per each 4-5 Fe atoms capable of binding one oxygen atom. This form is impossible to obtain by O 2 adsorption or NO decomposition. Surface oxygen generated by …
