A catalytic composition for treating a NOx-containing exhaust gas, wherein the composition comprises a copper-substituted small-pore zeolite comprising: i) Ce and/or La in a total amount of about 5 to about 400 g/ft; and ii) Nd and/or Nb in a total amount of about 5 to about 400 g/ft.

Catalytic composition

The present disclosure relates to a method for forming a catalyst article comprising: (a) forming a plastic mixture having a solids content of greater than 50% by weight by mixing together a crystalline small pore or medium pore molecular sieve in an Hor NHform, an insoluble active metal precursor, an inorganic matrix component, an organic auxiliary agent, an aqueous solvent and optionally inorganic fibres; (b) moulding the plastic mixture into a shaped article; and (c) calcining the shaped article to form a solid catalyst body. The present disclosure further relates to a catalyst article, particularly a catalyst article which is suitable for use in the selective catalytic reduction of nitrogen oxides, and to an exhaust system.

Method for forming a catalyst article

The invention relates to a catalytic article comprising a substrate having an inlet and an outlet; a first coating comprising a blend of: (1) platinum on a support, and (2) a first SCR catalyst; and a second coating comprising a second SCR catalyst; wherein the support comprises at least one of a zeolite or a SiO&#x2014;AlOmixed oxide. The platinum may be fixed on the support in solution.

Ammonia slip catalyst with in-situ PT fixing

The invention relates to a catalytic article comprising a substrate having an inlet and an outlet; a first coating comprising a blend of: (1) platinum on a support, and (2) a first SCR catalyst comprising a Cu- and Mn-exchanged molecular sieve; and a second coating comprising a second SCR catalyst; wherein the support comprises at least one of a zeolite or a SiO-AlOmixed oxide. The platinum may be fixed on the support in solution.

A catalyst composition for treating an exhaust gas, the catalyst composition comprising a molecular sieve, the molecular sieve comprising exchanged copper and exchanged manganese.
