dc.description	The macromolecular complexes Chitosan?(PtCl2)n and PSP-co-4-PVP?(PtCl2)n, were prepared from the respective polymer and PtCl2 in metal:polymer molar ratios 1:1 and 1:5. Pyrolisis of the macromolecular complexes Chitosan?(PtCl2)n and PSP-co-4-PVP?(PtCl2)nat 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.
