摘要：
Ru-FAU samples were prepared by wet impregnation and studied as promising catalysts for NO oxidation. The existence of rare earth ions in FAU structure showed positive effect on NO oxidation while the existence of alkali metal ions on cation sites showed negative effect. As a result, Ru-REY exhibited the best activity and a maximal NO conversion of ca. 94% was obtained at 250 °C at a very high WHSV of 180,000 h−1.
