OXIDATION FACILITY BY A TEMPERATURE DEPENDENCE ON THE METAL NOBLE NANOSTRUCTURED M°/M_xO_y PHASE PRODUCTS USING A SOLID STATE METHOD: THE CASE OF Pd. J. Chil. Chem. Soc. [online]. 2016, vol.61, n.4, pp.3273-3276. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072016000400024.

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.
