Towards High-Temperature Fuel Cells using Sulfonated-Phosphonated Poly(pentafluorostyrene)

Chemical Communications, Год журнала: 2025, Номер unknown

Опубликована: Янв. 1, 2025

Herein, we present a hybrid polymer material with phosphonic acid and sulfonic moieties on poly(pentafluorostyrene) backbone utilizing the SNAr Michaelis-Arbuzov para-fluoro-thiol reaction. Blending benzimidazole yielded mechanically stable membrane featuring proton conductivities up to three times higher than conventional Nafion N211 at temperatures above 120 °C.

Designing high-performance transition-metal electrocatalysts with controlled active heterointerfacial sites for catalyzing the electrochemical oxygen evolution reaction (OER) is very desirable but remains a great challenge. Here, facile strategy synthesis of nitride-based interfacial boron-doped cobalt/cobalt nitride (B-Co/Co2N) demonstrated optimal heterointerfaces between Co and Co2N by introducing boron as dopant to former. Benefiting from unique electronegativity B, obtained B-Co/Co2N show excellent OER performance overpotential inputs low 262 310 mV 10 100 mA cm-2, which are 1.4 6.6 times higher than those Co/Co2N same potential input, respectively. The experimental theoretical results demonstrate role B in inducing charge redistribution region, downshift 3d band center, oxidation state *OOH formation, lower energy barriers. Furthermore, assembled electrolyzer can steadily produce an industrial-grade current density 1000 cm-2 at cell voltage input only 1.81 V least h Faradaic efficiency near 100%. This study provides promising heteroatom-doped high environmental applications.
