A monolithic catalyst for simultaneous removal of NOx and carbon particles, comprising:

• a monolith,
• wherein the monolith comprises Cr—Ni acid-proof austenitic steel foil
• wherein the austenitic steel foil includes 1H18N9T/1.4541,
• wherein the monolith includes a plurality of monolith channels,
• wherein each channel includes at least one channel surface bounding the respective channel
• a monolithic catalyst,
• wherein the monolithic catalyst comprises a two phase catalyst;
• wherein the catalyst is operative to provide an oxygen layer on the monolithic catalyst,
• wherein the oxygen layer is located on the at least one channel surface of each of the respective plurality of monolith channels,
• wherein the at least one channel surface of each of the plurality of monolith channels further includes NiFe2O4 andFe2O3(Mh) phases with spinel structure,
• wherein the phases include micro-crystallites, additionally containing Mn.

A method comprising:

• a) oxidizing a monolith,
• wherein the monolith comprises Cr—Ni acid-proof austenitic steel foil
• wherein the austenitic steel foil includes 1H18N9T/1.4541,
• wherein oxidation of the monolith creates at least one oxide layer on the foil,
• b) washing the at least one oxide layer of the monolith with a solution including nickel ions,
• c) annealing the monolith in an oxidizing atmosphere,
• d) introducing nickel ions into the at least one oxide layer by annealing the monolith in an oxidizing atmosphere in (c),
• e) reducing the at least one oxide layer,
• f) subsequent to (e), producing a product from the processed monolith material of (e).
