FIELD: engines and pumps.
SUBSTANCE: invention relates to catalysis. Proposed method of production of said catalytic neutralisers of ICE comprising the carrier composed of cylindrical metal block. Said block accommodates the matrix made of twisted corrugated metal foil of stainless steel. Said carrier is coated with oxide composite ply containing oxides and hydroxides of aluminium, zirconium and lanthanum in the form of suspension. Note here that said oxide composite ply comprises precursors of catalytically active phase at the ratio Pt(Pd):Re(Ru)=1:1, total metal content making 0.53-0.88 g/dm3. Excess suspension is blown off by compressed air. Said suspension is repeatedly applied unless preset specimen weight is reached to make thermal treatment in muffle kiln at 400-700°C for 4-6 hours.
EFFECT: high dispersity catalytic neutraliser, uniform distribution of catalytically active components over the surface.
