Targeted accelerated aging of precious metal-containing three-way catalyst with a catalytic coating of precious metal of e.g. platinum and/or palladium, where after a hydrothermal aging, a defined reactivation degree of rhodium is achieved

摘要

Process for targeted accelerated aging of precious metal-containing three-way catalysts with a catalytic coating of the precious metal of rhodium, platinum and/or palladium, where after a hydrothermal aging, a defined reactivation degree of rhodium is achieved by at least one reduction parameter, is claimed.
