Abstract
A method of depositing catalytically active components on high-surface carrier materials is disclosed by dispersing the carrier materials in water and mixing this dispersion with an aqueous solution of soluble precursors of the catalytically active components. The pH of the dispersion is adjusted to a value between 6 and 8 before the aqueous solution of the precursors is supplied by capillary injection under constant agitation of the dispersion and thereafter, if necessary, the precursors of the catalytically active components are precipitated on the carrier material by capillary injection of a dilute base.
