• Resumen

  • Pyrolysis at 800°C under air of the macromolecular precursor Chitosan•(PdCl2)n and PS-co-4-PVP•(PdCl2)n in solid state afford the mixture phases Pt/PdO depending on the molar ratio metal/polymer. For the 1:1 Chitosan•PdCl2)n and PS-co-4-PVP•(PdCl2)n precursors the pure phase PdO was obtained while that for another molar ratios 1:5 and 1:10, the mixture phase Pt/PdO were obtained. For the 1:10 PS-co-4-PVP•(PdCl2)n precursor the core/shell PdO@Pd nanoparticles as small as 4 nm were observed. Optical properties for the PdO indicate an insulator behavior.
