Abstract

Ionomer binders are highly important for maximizing the performance of nanoparticle catalysts, yet their development has received limited attention. In this study, novel fluorine-free anion-exchange copolymer and terpolymer-based ionomers containing cyclic and rigid structures were designed to enhance ion conductivity and free volume, thereby promoting rapid mass transport and improved reaction kinetics for the alkaline HER.
