Title
A Ce–Cu–Ti oxide catalyst for the selective catalytic reduction of NO with NH3
Abstract

A Ce–Cu–Ti complex oxide catalyst for the selective catalytic reduction of NO with NH3 was prepared by coprecipitation method. XRD and H2–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.
