A Ce-Cu-Ti oxide catalyst for the selective catalytic reduction of NO with NH3

A Ce-Cu-Ti complex oxide catalyst for the selective catalytic reduction of NO with NH3 was prepared by coprecipitation method XRD and H-2-TPR reveal that the strong interaction between Ce and Cu results in the production of a new active oxygen species with high reducibility at low temperatures Compared with Ce-Ti oxide catalyst the Ce-Cu-Ti oxide catalyst produces better performance at the temperatures lower than 350 C and higher SO2-resistent ability H2O will reduce the SCR activity of Ce-Cu-Ti catalyst at low temperatures while promoting the catalyst performance at temperatures more than 350 C (C) 2010 Elsevier B V All rights reserved
