Abstract
A pretreatment method of nitric acid pickling is applied in the fabrication of Cu-Ag core-shell nanoparticles. By tuning the pH value and the concentration of Cu ions after acid pickling, the cleaning and separation process can be eliminated. This simplified pretreatment process can prevent the oxidation and particle loss. The as-prepared Cu@Ag nanoparticles show promising coating quality, oxidation resistance and quasi-spherical core-shell microstructure. Such a pretreatment method provided by this study could be promising in further rapid fabrication of Cu-Ag core-shell nanoparticles.
