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

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(22), P. 10434 - 10442

Published: May 21, 2024

Pt-containing meta- and para-linked poly(phenyleneethynylene)s were synthesized by the dehydrochlorination coupling polymerization of PtCl2(PBu3)2 with m- p-diethynylbenzenes. The formed polymers sintered at 900 °C to obtain Pt–graphene hybrids, whose structures examined Raman scattering spectroscopy, X-ray photoelectron spectroscopy (XPS), diffraction (XRD) measurements. Shapes─facets, terraces, steps─with average diameters 2.0–3.4 μm observed field emission scanning electron microscopy (FE-SEM). hybrids moderately adsorbed CO2 O2 slightly ethylene methane. Epoxidation stilbene was carried out using as catalysts oxide.

Substituent Effect in Determining the Total Structure of an All-Alkynyl-Protected Ag₉₈ Nanocluster for Methanol Tolerant Oxygen Reduction Reaction

Chemical Science, Journal Year: 2024, Volume and Issue: unknown

Published: Jan. 1, 2024

A sterically demanding ortho -CF 3 substituent defines not only the arrangement of ligands on a Ag 98 (2-CF PhCC) 48 Cl 4 nanocluster (Ag98) but also inter-cluster interactions. Ag98 shows excellent methanol tolerance in oxygen reduction reaction.
