💡 Novelty & Significance:
TFE decouples acidity from interfacial reactivity in Li-NRR, suppressing parasitic hydrogen evolution despite high acidity via fluorinated interfacial passivation and a crystalline LiF-rich SEI. Blending with ethanol optimizes proton activity, achieving 59.0% Faradaic efficiency in flow and 82.8% at high pressure. This establishes proton-donor engineering as a strategy to tune SEI nanostructure for selective ammonia synthesis.
