首尔国立大学研究团队发现了一个影响电化学反应的隐藏因素——电极附近的局部pH变化。1由教授Jaeyune Ryu领导的研究小组通过优化反应器设计来控制电极周围的酸碱度环境，将Baeyer-Villiger氧化反应的选择性从16%提高到97%。1这项发现为利用氧气和电力替代有害过氧化剂进行化学合成开辟了新路径。1
研究人员通过改进装置参数显著提升了反应效率。1将电极距离从20毫米减少到4毫米，生产速率增加约2.2倍；在流速最低到最高的条件下，单位时间产出增加约14倍。1在优化条件下，ε-己内酯的产率达到82%，可用于生产可生物降解聚合物。1电极附近的pH范围波动显著，阴极附近可达到11，阳极附近则低至2.5。1
为了验证这一原理的广泛适用性，研究人员检查了自2010年以来发表的600多篇论文，发现约89%的研究涉及电子和质子的双重转移反应。1该技术有望应用于塑料、药物和电子材料的制造。1相关研究论文已发表在《美国化学学会期刊》（JACS）2026年第148卷第37期，获得首尔国立大学、韩国国家研究基金和基础科学研究所的支持。1
Researchers at Seoul National University have identified local pH variations near electrodes as a critical determinant in electrochemical reactions, a discovery that could revolutionize the production of plastics, pharmaceuticals, and electronic materials.1 By optimizing reactor design to control acidity levels around the electrode—where pH can range from 11 near the cathode to 2.5 near the anode—the team transformed the selectivity of the Baeyer-Villiger oxidation reaction from 16% to 97%.1
The research, led by Professor Jaeyune Ryu at the School of Chemical and Biological Engineering, demonstrates the practical impact of this principle through multiple enhancements.1 Reducing the electrode distance from 20 millimeters to 4 millimeters increased the production rate approximately 2.2-fold, while adjusting flow conditions yielded output increases of roughly 14-fold under optimal settings.1 The method employs oxygen and electricity instead of harmful peroxide compounds, achieving a yield of 82% for epsilon-caprolactone, a compound used in biodegradable polymers.1 An analysis of over 600 papers published since 2010 revealed that approximately 89% involved reactions requiring dual transfer of electrons and protons, suggesting the team's findings have broad applicability across the field.1 The study, supported by Seoul National University, the National Research Foundation of Korea, and the Institute for Basic Science, was published in the Journal of the American Chemical Society, Volume 148, Issue 37, in 2026.1
