Preferential adsorption of ethylene oxide on Fe and chlorine on Ni enabled the electrosynthesis of ethylene chlorohydrin (ECH) with high conversion and selectivity. Scalable production of 185.1 mmol of ECH with 92.5 % yield at 55 mA cm−2 in 1 h, paired synthesis of ECH and 4-amino-3,6-dichloropyridine-2-carboxylic acid (an herbicide), and successful fabrication of a series of other chloro- and bromoethanols
环氧乙烷优先吸附在 Fe 上,氯优先吸附在 Ni 上,使电合成乙烯氯醇 (ECH) 具有高转化率和选择性。在 1 小时内在 55 mA cm -2 下大规模生产 185.1 mmol ECH,产率为 92.5%,ECH和 4-amino-3,6-dichloropyridine-2-carboxylic acid(一种除草剂)的配对合成,并成功制造了一系列其他氯乙醇和溴乙醇突出了潜在的效用。
