Abstract

A simple method to prepare cobalt nanoparticles (CoNPs) in an aqueous environment was developed utilizing 4-aminophenol as a reducing agent and the gemini surfactant (14-4-14)/polyvinylpyrrolidone (PVP) as a stabilizer. The localized surface plasmon resonance band of cobalt nanoparticles in the UV-Vis spectrum was used to determine the rate of formation of cobalt nanoparticles and to assess the beginning of the oxidation process. The effect of the concentration cobalt nitrate, 4-aminophenol, 14-4-14 and PVP was investigated on the growth rate of CoNPs. The data obtained in this work provide valuable information on the rate of reaction at the nanoscale.

Kurzfassung

Ein einfaches Verfahren zur Herstellung von Cobalt-Nanopartikeln (CoNPs) in einer wässrigen Umgebung wurde unter Verwendung von 4-Aminophenol als Reduktionsmittel und einer Gemini-Tensid (14-4-14)-Polyvinylpyrrolidon (PVP)-Mischung als Stabilisator entwickelt. Das lokalisierte Oberflächen-Plasmon-Resonanzband von Cobalt-Nanopartikeln im UV-Vis-Spektrum wurde verwendet, um die Geschwindigkeit der Bildung von Cobalt-Nanopartikeln und den Beginn des Oxidationsprozesses zu bestimmen. Die Wirkung der Konzentrationen von Cobaltnitrat, 4-Aminophenol, 14-4-14 und PVP auf die Wachstumsgeschwindigkeit von CoNPs wurde untersucht. Die in dieser Arbeit erhaltenen Daten liefern wertvolle Informationen über die Geschwindigkeiten von Reaktionen im Nanometerbereich.
