Comparative Structural Studies of the Silver and Nickel Nano Composites Synthesized by Chemical Methods

Silver and nickel nanoparticles were synthesized from urea and formaldehyde by using chemical method, followed by calcination at 8000C. The chemical composition and crystallographic structure of silver and nickel nanoparticles were confirmed by XRD. Surface imaging studies like AFM was carried out for understanding surface morphology and particles size distribution. The spherical and porous-like morphology of silver and nickel nanoparticles were confirmed by SEM and TEM. White spots are observed because of the the presence of silver and nickel metal ions in spherical forms. The particles size of silver and Nickel metal ions obtained through XRD are found to be 41.43 nm and 13.71 nm respectively.
