A method for the preparation of a catalysed monolith zone coated with different catalysts, comprising the steps of a) providing a porous monolith substrate with a plurality of longitudinal flow channels separated by gas permeable partition walls, the monolith substrate having a first end face and at a distance to the first end face a second end face; b) providing a first sol solution in an amount corresponding to at least the pore volume in a first catalyst zone of the gas permeable partition walls to be coated with the first sol solution, the first sol solution containing water soluble or suspended precursors of one or more catalytically active compounds and water soluble or suspended precursors or oxides of one or more metal oxides catalyst carrier compounds, at least one of the one or more precursors or oxides is suspended and at least one of the one or more precursors is dissolved in the sol solution; c) providing a second sol solution in an amount corresponding to at least the pore volume in a second catalyst zone of the gas permeable partition walls to be coated with the second sol solution, the second sol solution containing water soluble or suspended precursors of one or more catalytically active compounds different to the catalytically active compounds in the first sol solution and water soluble or suspended precursors or oxides of one or more metal oxides catalyst carrier compounds, at least one of the one or more precursors or oxides is suspended and at least one of the one or more precursors is dissolved in the second sol solution; d) placing the porous monolith substrate substantially vertically in a container containing the amount of the first sol solution and dipping the first end face facing the first catalyst zone into the first sol solution; e) sucking up the amount of the first sol solution solely by capillary forces into pores of the permeable partition walls from the first end face without applying vacuum or pressure into pores of the first zone; f) subsequently inverting the porous monolith substrate and placing the porous monolith substrate substantially vertically in a container containing the amount of the second sol solution and dipping the second end face facing the second catalyst zone into the second sol solution; g) sucking up the amount of the second sol solution solely by capillary forces into pores of the permeable partition walls from without applying vacuum or pressure into pores of the second zone; and h) drying and calcining the thus coated monolith substrate. a) providing a porous monolith substrate with a plurality of longitudinal flow channels separated by gas permeable partition walls, the monolith substrate having a first end face and at a distance to the first end face a second end face; b) providing a first sol solution in an amount corresponding to at least the pore volume in a first catalyst zone of the gas permeable partition walls to be coated with the first sol solution, the first sol solution containing water soluble or suspended precursors of one or more catalytically active compounds and water soluble or suspended precursors or oxides of one or more metal oxides catalyst carrier compounds, at least one of the one or more precursors or oxides is suspended and at least one of the one or more precursors is dissolved in the sol solution; c) providing a second sol solution in an amount corresponding to at least the pore volume in a second catalyst zone of the gas permeable partition walls to be coated with the second sol solution, the second sol solution containing water soluble or suspended precursors of one or more catalytically active compounds different to the catalytically active compounds in the first sol solution and water soluble or suspended precursors or oxides of one or more metal oxides catalyst carrier compounds, at least one of the one or more precursors or oxides is suspended and at least one of the one or more precursors is dissolved in the second sol solution; d) placing the porous monolith substrate substantially vertically in a container containing the amount of the first sol solution and dipping the first end face facing the first catalyst zone into the first sol solution; e) sucking up the amount of the first sol solution solely by capillary forces into pores of the permeable partition walls from the first end face without applying vacuum or pressure into pores of the first zone; f) subsequently inverting the porous monolith substrate and placing the porous monolith substrate substantially vertically in a container containing the amount of the second sol solution and dipping the second end face facing the second catalyst zone into the second sol solution; g) sucking up the amount of the second sol solution solely by capillary forces into pores of the permeable partition walls from without applying vacuum or pressure into pores of the second zone; and h) drying and calcining the thus coated monolith substrate.
