Surface nitrile group functionalized multi-walled carbon nanotubes supported Pt nanocomposites were prepared by the reduction of hexachloroplatinate acid in glycol solution suspended surface functionalized multi-walled carbon nanotubes. Average particle sizes of Pt nanoparticles were estimated by XRD method and TEM micrographs. The data show narrow distribution of the particle size of the Pt nanoparticles...
FexPt100-x nanoparticles were synthesized by thermal decomposition of iron pentacarbonyl and reduction of platinum acetylacetonate. The structural and magnetic properties of the nanoparticles with controlled particle size and shape were studied. The nanoparticles show superparamagnetic behavior. The particles also show hard magnetic properties with coercivity of more than 12 kOe after annealing. HRTEM...
The SiO2 and SiO2-Ag0 nano-spheres by sol-gel method have new application in the field photonics crystals. In this report, we demonstrate the synthesis of silver particles by reduction Ag+, obtained nanoparticles with range of size 2-10 nm, on colloid silica sphere, the silver nanoparticles, appearing on the surface of the silica microsphere. The material morphology was examined by electron microscopy...
