摘要： The invention relates to a catalyst substrate made of a porous inorganic material for treating exhaust gas, having a honeycomb structure, one of the surfaces of the structure enabling the intake of exhaust gas to be treated and the other surface enabling the discharge of the treated exhaust gas, and comprising, between said intake and discharge surfaces, an assembly of pipes or adjacent channels with parallel axes therebetween, separated by porous walls, said substrate being coated on at least a portion of the inner surface thereof with at least one polymer or a vinylpyrrolidone copolymer.
