A method for the preparation of a catalysed monolith, 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) in a container providing a sol solution at least in an amount corresponding to pore volume of the gas permeable partition walls, the sol solution containing a water soluble or colloidal precursor of one or more catalytically active compounds and a water soluble or colloidal precursor of one or more metal oxides catalyst carrier compounds, at least one of the one or more precursors is colloid and at least one of the one or more precursors is water soluble; c) placing the monolith substrate substantially vertically in the container with the first or second end face dipped into the sol solution; d) sucking up the sol solely by capillary forces into pores of the permeable partition walls from the end face dipped into the sol solution without applying vacuum or pressure to a predetermined distance in the permeable partition walls from the end face dipped into the sol solution; e) subsequently inverting the monolith substrate and placing the monolith substrate substantially vertically in the container with the opposite end face dipped into the sol solution; f) sucking up the sol solely by capillary forces into pores of the permeable partition walls from the opposite end face dipped into the sol solution without applying vacuum or pressure; and g) 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) in a container providing a sol solution at least in an amount corresponding to pore volume of the gas permeable partition walls, the sol solution containing a water soluble or colloidal precursor of one or more catalytically active compounds and a water soluble or colloidal precursor of one or more metal oxides catalyst carrier compounds, at least one of the one or more precursors is colloid and at least one of the one or more precursors is water soluble; c) placing the monolith substrate substantially vertically in the container with the first or second end face dipped into the sol solution; d) sucking up the sol solely by capillary forces into pores of the permeable partition walls from the end face dipped into the sol solution without applying vacuum or pressure to a predetermined distance in the permeable partition walls from the end face dipped into the sol solution; e) subsequently inverting the monolith substrate and placing the monolith substrate substantially vertically in the container with the opposite end face dipped into the sol solution; f) sucking up the sol solely by capillary forces into pores of the permeable partition walls from the opposite end face dipped into the sol solution without applying vacuum or pressure; and g) drying and calcining the thus coated monolith substrate. <EOS>
