Sintering of Platinum-Containing Conjugated Polymers: Gas Adsorption and Catalysis of the Formed Pt-Carbon Composites.

Pt-containing - and -linked poly(phenyleneethynylene)s were synthesized by the dehydrochlorination coupling polymerization of PtCl(PBu) with - and -diethynylbenzenes. The formed polymers were sintered at 900 °C to obtain Pt-graphene hybrids, whose structures were examined by Raman scattering spectroscopy, X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) measurements. Shapes─facets, terraces, and steps─with average diameters of 2.
