Resumen

Ptx-Pd(1-x) nanoparticles supported on amorphous silica (SiO2) were prepared by wetness impregnation techniques with choroplatinic acid (H2PtCl6) and palladium chloride (PdCl4) with different concentrations of Pt and Pd at about 1% in overall metallic weight. The structural and physic characterization of these samples were carried out by BET Surface Area, X-Rays Diffraction (XRD), Transmission Electron Microscopy (TEM), attach with X-Ray and Energy Dispersive Spectroscopy (XEDS). In this work, we observed the distribution of Pt and Pd in nanoparticles. By XRD Ptx-Pd(1-x) Nanoparticles are made of a single solid solution of Pt and Pd atoms, and the particles diameter of about 4 nm was estimated by HREM and Bright field image. Energy dispersive X-ray spectrometry (XEDS) allowed to determine that Pt-Pd nanoparticles were found mainly to have cubeoctahedral shape with fee packing and their values were found to be close to the stochiometric relative concentrations in weight of the metals, in the precursor aqueous solution.
