Abstract:A crystalline porous Ni-MOF catalyst was fabricated successfully through hydrothermal method and shown to exhibit excellent catalytic performance for NH3-SCR. This prepared Ni-MOF showed better thermal stability than other reported Cu-BTC or MIL-100(Fe) SCR catalyst material. It could keep a satisfactory stable crystalline structure when the reaction temperature reached up to 440 degrees C. Moreover, it was found that the catalytic activity of Ni-MOF was significantly improved after preheat treatment in N-2 atmosphere. The Ni-MOF catalyst activated at 220 degrees C achieved more than 92% NO conversion efficiency with a large operating-temperature window from 275 to 440 degrees C.
