摘要:
A three way catalyst includes an extruded solid body having by weight: 10-100% of at least one binder/matrix component; 5-90% of a zeolitic molecular sieve, a non-zeolitic molecular sieve or a mixture of any two or more thereof; and 0-80% optionally stabilised ceria. The catalyst also includes at least one precious metal and optionally at least one non-precious metal, wherein: (i) the at least one precious metal is carried in one or more coating layer(s) on the body surface; (ii) at least one metal is present throughout the body and at least one precious metal is carried in one or more coating layer(s) on a body surface; or (iii) at least one metal is present throughout the body, is present in a higher concentration at a body surface, and at least one precious metal is carried in one or more coating layer(s) on the body surface.
