Eine einfache und effektive Methode zur Synthese von Nanopartikeln, die auf extremer kathodischer Polarisation eines Metalls, Bildung von kationisch stabilisierten Metallanionen und ihrer Agglomeration beruht, wird vorgestellt (siehe Bild). Am Beispiel von Platin wird die verbesserte katalytische Aktivität dieser Nanopartikel bei der Oxidation von Kohlenmonoxid sowie Methanol gezeigt.
