Abstract

original image

Tetracyanchinodimethan (TCNQ) auf Silbernanopartikeln (AgNPs) induziert hohe positive Oberflächenladungen, die einen Grenzflächendipol erzeugen, über den sich die Energieniveaus der AgNPs einstellen lassen (siehe Bild). Poly(vinylpyrrolidon)-Membranen, die dispergierte AgNPs mit TCNQ enthalten, zeigen eine hohe Selektivität bei der Trennung gasförmiger Olefin-Paraffin-Gemische.
