BIMETALLIC AU/AG METAL SUPERSTRUCTURES FROM MACROMOLECULAR METAL COMPLEXES IN SOLID-STATE

Novel bimetallic Au/Ag superstructures have been prepared from solid-state pyrolysis of the macromolecular complexes Chitosan(MLn/M'Ln)n y PSP-4-PVPx( MLn/M'Ln)n with MLn = AuCl3 and M'Ln = Ag(CF3SO3)The characterization was made from XRD (X-ray diffraction of powder), SEM and EDS ana...
