영문 초록

In this study, we examined the effect of NO addition on the ozone-induced soot oxidation activity of LaMnO 3 perovskite catalysts. The addition of 10~20% NO (NO 2 ) with respect to the concentration of ozone effectively enhanced the rate of ozone-induced soot oxidation rate over LaMnO 3 . However, the excessive addition of NO (NO 2 ) was detrimental to ozone-induced soot oxidation activity. It is supposed nitrogen oxides would adsorb on the catalyst and then react with carbon-oxygen species developed on soot surface, but an excessive addition of nitrogen oxide would inhibit the formation of carbon-oxygen species, which is a key intermediate in the reaction, and consequently suppress the oxidation rate of soot.
