Trägerfixierte Nanoplättchen bestehend aus einer Gold-Silber-Legierung (siehe Bild) wurden durch Abscheidung von Silber-Nanoplättchen auf einem Galliumarsenid-Wafer und anschließendes Überwachsen und Legieren mit der Goldkomponente synthetisiert. Die hohe spezifische Oberfläche der Nanoplättchen sorgt für eine hohe katalytische Effizienz dieses Materials.
