Abstract (en)
[origin: WO2021084140A2] The invention relates to a method for producing a particulate carrier material provided with silver and ruthenium, comprising the following steps: a) providing a water-insoluble particulate carrier material and aqueously dissolved silver and ruthenium precursors, b) bringing the particulate carrier material into contact with the aqueous solution of the precursors to form an intermediate, c) bringing the intermediate into contact with an aqueous hydrazine solution having a pH value of >7 to 14 to form a mass comprising silver and ruthenium, d) optionally washing the obtained mass, and e) removing water and other possible volatile components from the mass.
