Al). No evidence of NO+ formation is observed over the siliceous zeolite samples. A working model of the reaction mechanism for the high-temperature NO oxidation reaction is proposed for acidic zeolites that is consistent with the observed form of the rate equation and the observed NO+ reaction intermediate.
It is shown that NO oxidation is catalyzed by chabazite zeolites in the proton (H + ), sodium (Na + ) and siliceous forms, by microporous carbons and by the metal-organic framework (MOF) material Basolite A100® at temperatures between 298K and 423K. Reaction orders at low conversion for NO and O 2 are 2 and 1, as observed for the gas-phase reaction. At higher conversion and...
