A stoichiometric reaction of benzene with the surface α-oxygen produced in N2O decomposition has been studied over FeZSM-5 zeolites. Products of this reaction were extracted from the surface and analyzed by chromatography. The reaction has been shown to proceed readily at room temperature resulting in nearly quantitative yield of phenol. This explains the unique catalytic properties of FeZSM-5 zeolites and their ferrisilicate analogs in the hydroxylation of aromatics by N2O. A “monoatomic oxidation” mechanism is suggested to explain the fact of partial but not complete oxidation upon participation of highly active α-oxygen in the reaction.
