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.Keywords
