Rational Ionomer Design Directs Hydrogenation Pathways and Reactant Accessibility in Electrochemical Nitrate Reduction
Ionomer engineering offers a powerful yet underexplored strategy for electrochemical nitrate reduction (NO3RR), since the polymer tailors the microenvironment at the catalyst surface. Here, we rationally design high-performance ionomers by applying fixed-charge sign and hydration as design criteria. Synthetic anion-e...
