An ethylenediamine-functionalized ionic liquid (IL) was synthesized for CO2 capture from industrial gases, with good CO2 absorption capacity of around 0.95 mmol (42 mg) of CO2/g of IL at 35 °C. In contrast to conventional gas desorption via utilization of an energy intensive thermal swing, CO2 was released on competitive complexation of the amines with cupric ions introduced to the ionic liquid electrolyte by the oxidation of a copper electrode. The electrolyte was regenerated by electrodeposition of cupric ions at the cathode. This work emphasizes the importance of electrodeposition from metal-containing ILs and the potential for new recyclable catalysts.

胺基离子液体，用于CO 2捕集以及电化学或热再生
乙二胺官能化离子液体（IL）为CO合成2从工业气体捕获，具有良好的CO 2周围0.95毫摩尔（42毫克）的CO的吸收容量2在35℃/克IL的。与通过利用能量密集的热波动的常规气体解吸相反，在胺与铜离子的氧化作用下引入到离子液体电解质中的铜离子竞争配位时，释放出CO 2。通过在阴极上电沉积铜离子来再生电解质。这项工作强调了从含金属的离子液体中进行电沉积的重要性以及新的可回收催化剂的潜力。
