Abstract

Themechanism of NO adsorption and oxidation over activated carbon at lowtemperature has been studied by NO adsorption and oxidation, NO2adsorption and Fourier transform infrared spectroscopy. The results show thatwhen oxygen is present, activated carbon catalyses NO oxidation into NO2and a stable NO conversion rate is achieved. NO is adsorbed in the form of (NO)2due to the confinement effects of the activated carbon micropore. (NO)2is oxidized into NO2 by oxygen. The disproportionation of NO2gives NO and NO3, that causes the peak of the maximum NOconcentration. When the active sites are saturated by NO3, NO2adsorption and disproportionation gradually diminish, that results in NO2breakthrough and increases the concentration of NO2 to thestationary one. At the same time, the concentration of NO gradually decreasesto the stationary one after the maximum.
