Abstract
The selective catalytic reduction of NO with C2H4 (C2H4-SCR) was inves tigated over perovskites containing Co, Mn, Fe, Cr, Al, Sn and Ti as h ost B-site cations. The C2H4-SCR activity was observed over Al-, Sn-an d Ti-based oxides which were free from redox-active metal cations such as Co and Cu and innately poor in oxidation activity. Over perovskite s containing redox-active metal cations, the undesirable consumption o f C2H4 by O-2 proceeded preferentially. (C) 1997 Elsevier Science B.V.
