Silver nanoparticles formation over Ti-Zr-Nb alloy via polyol synthesis

Abstract

Ag nanoparticles (AgNPs) were formed over the surface of novel superelastic Ti-Zr-Nb alloy via polyol synthesis at room temperature. Two synthesis media were used for AgNPs formation: ethylene glycol (EG) and polyethylene glycol (PEG-400). AgNPs formation rate in different polyols was evaluated by UV-VIS spectroscopy. Based on the obtained results higher formation rate was ascribed to PEG-400. Morphology of the material's surface, as well as chemical composition, were analyzed by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). It was demonstrated that the usage of PEG-400 as synthesis media facilitates the formation of more monodisperse AgNPs evenly distributed over the alloy’s surface.
