wire woven catalyst network from the precious metal alloys of platinum rhodium or platinum / rhodium / / palladium

摘要

Catalyst nets having an enlarged surface area can be produced from a wire of, for example, Pt90Rh10 by coating the wire with base metal, heat treatment with partial transformation of Pt90Rh10 into solid solutions with the base metal, dissolution of the base metal and weaving of the wire. They are suitable for the oxidation of ammonia and for the ammoxidation of methane.
