Abstract

A carrier-supported catalyst is prepared by applying a noble metal on to a ceramic honeycomb structure coated with an aluminum oxide layer. To this end, the ceramic honeycomb structure is impregnated with an aqueous solution containing nitrilotriacetic acid or ethylenediaminotetraacetic acid, ammonia and at least one noble metal compound.
