摘要：
An article for treating a gas containing nitrogen oxides including: (a) a monolith substrate; and (b) a catalytic composition containing at least one catalytic component consisting of (i) at least one transition metal dispersed on a mixed oxide or composite oxide or a mixture thereof as support material consisting of cerium and zirconium; or (ii) cerium oxide and zirconium oxide as single oxides or a composite oxide thereof or a mixture of the single oxides and the composite oxide dispersed on an inert oxide support material, wherein at least one transition metal is dispersed thereon, provided that at least one selected transition metal is tungsten, wherein the catalytic composition is disposed on the monolith substrate.
