金纳米粒子的制备及其在碳钢电极表面自组装研究
Study on Synthesis of Gold Nanoparticles and Their Self-assembled Films on the Surface of Electrode
摘要
Abstract
This article describes a simple approach to synthesize Au nanoparticle chains by reducing HAuCl4 with sodium citrate in absence of any additional capping agent or surfactants.UVvis spectrophotometry and scanning electron microscopy (SEM) were employed to characterize assynthesized nanoparticles.The Au nanoparticles were assembled onto the surface of 20 carbon steel electrode by different cross-linking agents such as polyvinylpyrrolidone (PVP),acryl-thiourea (ATU) and thiourea (TU).Polarization curves and electrochemical impedance spectroscopy were used to detect the corrosion inhibition of the self-assembled Au nanoparticle films onto the the carbon steel electrode.The influences of the cross-lingking agents and assemble time on the films were also explored.The results show that all Au nanoparticle films assembled by different cross-linking agents had good corrosion inhibition,in which Au nanoparticles assembled for 12 h by ATU had the highest corrosion inhibition efficiency of 99.15 %.关键词
