Selective catalytic reduction over Cu-exchanged X zeolite catalyst: in situ DRIFTS and DFT studies of NH3-SCR mechanism

Due to the ultra-high specific surface area of X zeolite contributing to catalytic sites and the Si/Al ratio in blast furnace slag being similar to that in X zeolite, the Cu-ion exchanged X zeolite catalyst prepared from blast furnace slag demonstrated excellent NH3-SCR activity, achieving about 95%...

Zusammenfassung:Due to the ultra-high specific surface area of X zeolite contributing to catalytic sites and the Si/Al ratio in blast furnace slag being similar to that in X zeolite, the Cu-ion exchanged X zeolite catalyst prepared from blast furnace slag demonstrated excellent NH3-SCR activity, achieving about 95% of NOx conversion in the temperature range of 150 °C to 500 °C.
