Abstract

The synthesis of polyvinylpyrrolidone (PVP) and decanethiol (DT) seed mediated Ag/Ru allied bimetallic nanoparticles were successfully carried out by the simultaneous reduction of the metal ions in aqueous and non-aqueous solutions with ethylene glycol (EG), diethylene glycol (DEG), glycerol (GLY) and pentaerythritol (PET). The TEM images of the AgRu NPs passivated by DT/DEG; DT/GLY; DT/EG (200 °C, 3h) and PVP/PET (90 °C, 4h) revealed novel well-ordered core-shell structures with particle sizes in the range of 8.2 0.7, 10.0 ±3.2,11.4 ±1.3 and 18.89 ±6.83 nm respectively. The analysis of the nanocomposites using X-ray photoelectron spectroscopy and X-Ray diffraction suggests dominance of the face-centered cubic structure with 2θ reflections slightly shifted from the silver peaks.
