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...

Water‐Mediated Proton Facilitation for Stable Acidic CO 2 Electrocatalysis

Electrochemical CO 2 conversion in acid can, in principle, maximize carbon efficiency but is typically undermined by facile hydrogen evolution. Moreover, operating at high current density often triggers a sharp local pH increase that propagates into the bulk electrolyte, causing an overall pH shift that erodes no...
