Pyrolisis of the macromolecular complexes Chitosan●(PtCl2)n and PSP-co-4-PVP●(PtCl2)n at 800 °C under air affords cubic nanostructured Pt in the pure phase. The morphology of the pyrolityc products depends on the molar metal:polymer ratio; i.e. a "cotton" 3D shape for the 1:1 ratio and a 'foamy" 3D shape for the 1:5 ratio. On the other hand, the particle size depends on the polymer nature, obtaining Pt nanoparticles as small as 6 nm for the chitosan precursors in both molar ratio.enNanoparticlesSolid StatePolymersPlasmonArtículo
