ABSTRACT:
The invention is directed to a method for enhancing the catalytic effectiveness of noble metal catalysts to reduce NO.sub.x and to oxidize hydrocarbons, which comprises: providing a solution of an organo noble metal compound dissolved in an organic solvent; impregnating a support material, preferably comprising at least 50% by weight .gamma.-alumina, with the solution; and heating the impregnated support material to evaporate the solvent and eliminate the organo group leaving the coated support material with the noble metal.
