Abstract

original image

Der Nachweis von Elektronen, die sich in Oberflächendefektzentren befinden, wird vorgestellt. Mit Tetracyanoethylen als Einelektronenakzeptor wurde die Reduktion von vollständig oxidiertem MoO3 charakterisiert. Durch Elektronentransfer gelangt negative Ladung zu auf der Oberfläche befindlichen Goldnanopartikeln, was die hohe katalytische Aktivität bei der aeroben Oxidation von Alkoholen erklärt.
