Abstract

original image

Löchrige Schale: Nanoporöse hohle Strukturen werden durch kontrollierte Zersetzung und Auflösung hergestellt. Die partielle thermische Zersetzung von Übergangsmetallsalzen erzeugt eine Metalloxidschale auf der Oberfläche der Metallsalzpartikel. Waschen mit Säure entfernt die Metallsalz-Kerne, und es entstehen hohle nanoporöse Metalloxidschalen (siehe Bild). Diese neue Strategie bietet eine templatfreie Route zu hohlen Strukturen ausgehend von einer einzigen Substanzquelle.
