TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The impregnation is carried out gradually starting from the inlet openings of the flow channels and/or zone wise, and/or zones of the respective flow channels are generated successively by the stepwise impregnation, and/or zones of the respective flow channels are successively impregnated in a cumulative manner one after another by the step wise impregnation. A concentration gradient of the catalytically active component is generated along the flow channels extending in the flow direction, a sloping and/or stepped concentration gradient is generated in the flow direction, and/or the concentration gradient of the respective inlet opening proceeds till the respective outlet opening of the flow channels. The stepwise impregnation is carried out by introducing or pumping the solution in the flow channels in a stepwise manner. The method includes maintaining the solution filled in the zones over a time duration, between two or more successive steps of impregnation. A same or a different time duration is adjusted between successive steps of impregnation, and/or the concentration gradient of the catalytically active component is generated along the flow channels extending in the flow direction, depending on the adsorption or chemisorption strength of the solution and the adjusted time duration. The stepwise impregnating is carried out by repeatedly introducing or pumping the solution into the flow channels at different filling levels. The filling levels correspond to zone boundaries of the successive zones and/or different concentrations of the solution are chosen for different filling levels. The concentration gradient of the catalytically active component is generated along the flow channels extending in the flow direction, depending on the concentration of the solution and the amount of the compound taken from the catalyst-shaped body. The method further comprises at least one step including (c1) deducing the excess solution from the flow channels, (c2) drying the impregnated catalyst-shaped body, (c3) calcining the impregnated catalyst-shaped body under a protective gas or argon at 750 degrees C, or (c4) converting the catalytically active component to the oxidation state 0, using hydrogen. Preferred Components: The compound is a chemisorptive compound or a precursor-compound of the catalytically active component and/or the compound is platinum-sulfite-acid or platinum-nitrate. The compound is optionally weak chemisorptive compound or precursor-compound of the catalytically active component, where the compound includes salts or compounds of platinum, palladium, gold, silver, ruthenium, rhodium, cobalt, nickel, vanadium, copper, iron, tungsten and/or manganese. The catalytically active component is a precious metal including platinum, palladium, gold, silver, ruthenium, rhodium, cobalt, nickel, vanadium, copper, iron, tungsten and/or manganese. The catalyst shaped body and/or the flow channels exhibit a carrier material, or are coated with the carrier material, where the carrier material is an open pore material, and/or the carrier material is an inorganic carrier material made of titanium oxide, gamma -aluminum oxide, theta -aluminum oxide, Delta -aluminum oxide, cerium oxide, silicon oxide, zinc oxide, magnesium oxide, aluminum-silicon oxide, silicon carbide, magnesium silicate, and/or zirconium oxide. The catalyst-shaped body is at least one element made of a carrier with parallel flow channels, a honeycomb body, a cordierite-honeycomb, or a metallic-honeycomb. The catalyst comprises the catalyst-shaped body containing multiple flow channels, which in each case have the inlet opening and the outlet opening, where the respective flow channels exhibit the concentration gradient of the catalytically active component extending in the flow direction. The concentration gradient of the catalytically active component forms the successive zones of the respective flow channels, and/or the concentration gradient includes the sloping and/or stepped concentration gradient in the flow direction, and/or the concentration gradient of the respective inlet opening proceeds till the respective outlet opening of the flow channels. EXAMPLE - Catalyst-shaped bodies were impregnated with aluminum oxide coated-cordierite honeycomb with platinum-sulfite-acid. Then, the coated catalyst-shaped bodies were calcined for 3 hours at 550 degrees C, which were further worked up to obtain a catalyst.
