- This study examined the oxidative removal of nitrogen oxides (NO) using a
MnO2 catalyst and ozone. A honeycomb MnO2 catalyst and ozone were used to
removal gaseous nitric oxide. There was negligible adsorption of NO on the
MnO2 catalyst in this experiment. However, all the NO gas supplied was oxidized
to NO2 when 50 ppm ozone and NO were supplied. Ozone decomposed to O* on
the MnO2 catalyst bed when added in excess. In addition, NO2, was effectively
oxidized to NO3
- by the O* formed from the decomposition of ozone. In particular,
there was 83% NO removal efficiency at normal temperatures. It is proposed that
the coupling of a MnO2 catalyst with ozone will provide a useful system for
removing nitrogen oxides.
