Single layer high perfomance catalyst

摘要

The invention relates to a single layer high performance catalyst containing on an inert carrier body a catalytic coating comprising platinum, rhodium and various oxide materials. The catalyst is characterised in that the catalytic coating comprises at least one first support material selected from the group comprising a first active alumina, ceria rich ceria/zirconia mixed oxide and a zirconia component, said at least one first support material being catalysed with a first part of the total platinum amount of the catalyst, and a second support material catalysed with the second part of the total platinum amount and with rhodium said second support material being a second active alumina.
