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

Pt-containing meta- and para-linked poly­(phenyleneethynylene)­s were synthesized by the dehydrochlorination coupling polymerization of PtCl2(PBu3)2 with m- and p-diethynylbenzenes.

Description
Summary:Pt-containing meta- and para-linked poly­(phenyleneethynylene)­s were synthesized by the dehydrochlorination coupling polymerization of PtCl2(PBu3)2 with m- and p-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 2.0–3.4 μm were observed by field emission scanning electron microscopy (FE-SEM). The Pt–graphene hybrids moderately adsorbed CO2 and O2 and slightly adsorbed ethylene and methane. Epoxidation of stilbene was carried out using Pt–graphene hybrids as catalysts to obtain stilbene oxide.
