华中科技大学「国家杰青」夏宝玉&南昌大学王红明&上海高等研究院宋飞最新JACS丨氢键网络调控酸性CO₂制乙醇！

TL;DR - A JACS study demonstrates a hybrid ionomer interface that controls proton transport during acidic CO₂ electroreduction, steering reactions toward ethanol while suppressing hydrogen and ethylene formation.

• The interface creates a stable, locally weak-alkaline environment in a bulk electrolyte at pH 1.
• Hydrogen-bond networks restrict H₃O⁺ diffusion and favor surface-*H-mediated Langmuir–Hinshelwood pathways over the ethylene-producing Eley–Rideal route.
• A membrane-electrode assembly achieved over 64% ethanol Faradaic efficiency at 200 mA cm⁻².
• The system operated stably for more than 350 hours.
