Abstract

original image

Kolloidale Pd@Pt-Nanopartikel mit einheitlichen Mesoporen sind in einer Stufe durch langsame Reduktion von Metallspezies in stark saurer Lösung zugänglich. In diesem System wirken F127-Micellen direkt als Template für die Mesoporen des Produkts; die bessere Reduzierbarkeit der Pd-Spezies führt zu den gewünschten Pd@Pt-Kern-Schale-Nanokolloiden.
