摘要

Abstract

G-C

was supported on the surface of foamed ceramic

and the g-C

@foamed ceramic was packed in the photocatalytic reactor in a layered manner. Effects of urea and H

concentration on NO conversion were investigated. Pulse experiments were carried out to investigate the change of NO conversion with time under different concentrations of H

. The contribution of each route that NO converted and the selectivities of products were calculated. Results showed that the photo-reduction of NO accounted for 2%

and the photo-oxidation of NO accounted for 14%

and the rest was absorbed by the humidifier. Products include ammonia (NH+ 4-N)

nitrogen (N

)

nitrite (NO-2-N) and nitrate (NO-3-N)

of which N

accounted for 9%.
