Abstract: A series of Cu+/Ni-MOF materials with different Cu loading were prepared by a hydrothermal method and were applied on selective catalytic reduction with NH3-SCR. From characterization results of XRD, XPS and TPR, it could be inferred that Cu(+)species have been successfully introduced into the Ni-MOF framework. Compared with monometallic Ni-MOF catalyst, all bimetallic Cu+/Ni-MOF sample showed much better NH3-SCR activity at low temperature and achieved about 30% increase in the maximum catalytic efficiency at 320 degrees C, which indicating a good synergistic effect between copper and nickel ions.
