Abstract

original image

Wiederbelebte Aktivität: Platinnanopartikel (Kuboktaeder, Würfel und poröse Partikel, im Bild von links nach rechts) mit Alkylammoniumionen als Bedeckung sind durch Manipulation der Reduktionskinetik zugänglich. Diese Nanopartikel sind katalytisch aktiver als Nanopartikel, deren Form mithilfe von Polymeren und anderen Metallionen gesteuert wurde.
