Abstract

original image

Schwefelgelb: Elementarer Schwefel wird als unkonventionelles Medium für die Synthese und Stabilisierung von kolloidalem Gold genutzt. In diesem System erfüllt Schwefel viele Funktionen, wie die Sulfurierung von PPh3 und die Solubilisierung und Reduktion von AuI-Vorstufen zu Au-Nanopartikeln (NPs; siehe Bild). Die Vulkanisation von Au-haltigen Schwefeldispersionen erfordert vernetzte Nanokomposite, die mit TEM, XRD, XPS und Raman-Spektroskopie nachgewiesen wurden.
