Abstract

Abstract : In this report, spectrophotometric, kinetic, and structural analysis has been carried out for the formation of cobalt nanoparticles (CoNPs) using 4-aminophenol as reducing agent. The localized surface plasmon resonance band (SPR) of cobalt nanoparticles in the UV–vis spectrum is used to determine the rate of formation of cobalt nanoparticles and assess the beginning of the oxidation process. The effect of cobalt nitrate, 4-aminophenol and TTAB concentration was investigated on the growth rate of cobalt nanoparticles. CoNPs were characterized by means of UV–vis, field emission scanning electron microscope (FESEM), and energy dispersive spectroscopy (EDS). The data obtained in this work provide valuable information on the rate of reactions at the nanoscale.
