Effects of hydrothermal aging on NH3-SCR reaction over Cu/zeolites

Publication year: 2012 Source: Journal of Catalysis, Available online 31 January 2012 Ja Hun Kwak, Diana Tran, Sarah D. Burton, János Szanyi, Jong H. Lee, … The effects of hydrothermal treatment on model Cu/zeolite catalysts were investigated to better understand the nature of Cu species for the selective catalytic reduction of NOxby NH3. After hydrothermal aging at 800 °C for 16 h, the NOxreduction performance of Cu-ZSM-5 and Cu-beta was significantly reduced at low temperatures, while that of Cu-SSZ-13 was not affected.
