Heterogeneous conversion of NO2 and NO on HNO3 treated soot surfaces: atmospheric implications
Overview & Synopsis
In the present study, the heterogeneous conversion of nitrogen oxide (NO) and nitrogen dioxide (NO2) was studied at atmospheric humidity levels on flame soot surfaces treated with gaseous nitric acid (HNO3). In addition, the heterogeneous reaction of HNO3 on soot was investigated at atmospheric humidity. For the treatment of soot by pure HNO3 only reversible uptake with a surface coverage of ~1-2x1014 HNO3 cm-2 was observed for HNO3 mixing ratios in the range 250-800ppbv. Only for higher HNO3 mixing ratios of >800ppbv the formation of NO and NO2 was observed. The results were not affected by the addition of NO. In none of the experiments with HNO3 the formation of nitrous acid (HONO) was observed. For HNO3 mixing ratios
