Ag Nanoparticles Self-Assembled Films On Iron Surface And Their Inhibition Properties, Zhang Zhe, Jia Ming-Zi, Ruan Le
Journal of Electrochemistry
The Ag nanoparticles were prepared in aqueous solutions through a chemical reduction method and transferred from water phase to toluene phase with the protection of 1-dodecanethiol (DDT). The polished iron electrode was immersed in the DDT-protected metal nanoparticles toluene solutions to form DDT/Ag nanoparticles self-assembled mixed films. Electrochemical methods such as electrochemical impedance spectroscopy and polarization curve measurement were used to study the inhibition properties of the self-assembled films in the 0.5 mol?L-1 H2SO4 solution. The appearance of elements such as S and Ag from the XPS data identified the presences of DDT and Ag nanoparticles.
