Synthesis of palladium nanoparticles in SiO2 matrix

Abstract

Palladium nanoparticles in SiO₂ matrix have been deposited by atom beam sputtering technique (ABS) using a gun as atom beam source. The concentration of Palladium in nanocomposite system has been varied from 10 at. % to 40 at.%. Structural characterizations Transmission electron microscopy (TEM) confirms the formation of spherical nanoparticles size varying from 2.2 Å to 3.8 Å. Structural characterizations Glancing Angle X-ray Diffraction (GAXRD) Studies & Selected Area Electron Diffraction(SAED) study confirms the crystallite nature of palladium nanoparticles. Energy Dispersive X-ray spectroscopy (EDX) technique confirms the presence of Palladium, silicon and oxygen.
