Abstract. A series of TiO2 supported catalysts were prepared by impregnation method in a rotary evaporator and evaluated for the oxidation of NO to NO2. Among all catalysts studied, Ru/TiO2 catalyst exhibited the best activity and a maximal NO conversion of c.a. 94% could be achieved at c.a. 275 oC at a high GHSV of 180,000 h-1. For ruthenium catalysts, the effects of supports, ruthenium l…
Abstract. The current research investigated N2O decompositions over the catalysts Ir/Fe-USY, Fe-USY and Ir-USY under various conditions, and found that a trace amount of iridium (0.1 wt%) incorporated into Fe-USY significantly enhanced N2O decomposition activity. The decomposition of N2O over this catalyst (Ir/Fe- USY-0.1%) was also partly assisted by NO present in the gas mixture, in contr…
