Beschreibung
Zusammenfassung:	The invention relates to a method for preparing a catalyst composition, wherein in an aqueous medium containing an iridium compound, at a pH 9, an iridium-containing solid is deposited on a support material, and the support material loaded with the iridium-containing solid is separated from the aqueous medium and dried, wherein, in the method, the support material loaded with the iridium-containing solid is not subjected to a thermal treatment at a temperature of more than 250° C. for a period of time of longer than 1 hour.
