摘要： The invention relates to a high performance catalyst containing a layer on an inert carrier body comprising noble metals from the platinum group deposited on support materials. The catalyst is characterised in that, the layer comprises platinum deposited in a washcoat consisting of Al203 which is stabilized with lanthana (La2O3), ceria (CeO2), which is stabilized with zirconia (ZrO2) and praseodymium (Pr6O11). The supprot is promoted by sulfur-containing compounds which come from at least one of following compounds: platinum sulfite (PtSO3), sulfuric acid (H2SO4), ammonium sulfate ((NH4)2SO4), titanium oxysulfate (TiOSO4), titanium sulfate (Ti2(SO4)3), and zirconium sulfate (Zr(SO4)2).
