Stabilizing ruthenium atom layer neighbors through molecular and metal support interactions for water electrolyzers

Abstract Designing catalysts that maximize both atomic efficiency and catalytic activity remains a central challenge in heterogeneous catalysis. While single-atom catalysts maximize noble metal utilization, their isolated structure limits the adsorption configurations of adsorbat...

Synergistic Engineering of Membrane–Electrode Interfaces via Surface Patterning in Anion Exchange Membrane Water Electrolysis

ABSTRACT The membrane–electrode interface critically governs the performance and durability of anion exchange membrane (AEM) water electrolysis, yet engineering these interfaces in pre‐formed hydrocarbon AEMs remains challenging due to their high glass‐transition temperatures and...

Plasma‐Engineered Polyethylene‐Reinforced Anion Exchange Membranes With Low Ionic Resistance and Low Hydrogen Crossover for Water Electrolysis

ABSTRACT Anion exchange membrane water electrolysis (AEMWE) enables low‐cost green hydrogen production but remains limited by the delicate balance among ionic resistance, gas crossover, and mechanical durability in hydrocarbon‐based membranes. Although reinforced composite membra...
