The manner of production of the monolithic catalyst for simultaneous removal of NOx and carbon particles, especially from off-gases of carbon power plants depends on the monolith is subject to oxidation after which the resulting oxide layers are washed with the solution of nickel salts; later the monolith is baked in the oxidising atmosphere with the view to inserting nickel ions into the oxide layer; finally this obtained oxide layers are subject to reduction.
