Electro-enzymatic conversion of CO offers a promising solution for CO utilization, while the conversion rate and efficiency were disappointing. To address the challenge, four kinds of natural deep eutectic solvents (NADES) with desirable biocompatibility were developed for the first time and used as the co-electrolyte in the electro-enzymatic conversion of CO. As a result, the SerGly-based solution presents high CO solubility and high electrocatalytic activity, compared to the conventional buffer. By applying SerGly in the electro-enzymatic conversion of CO, the yield of the product (methanol) is two times higher than that in the Tris-HCl buffer (0.22 mM) and 16 times higher than the control reaction.
电催化一氧化碳转化为一氧化碳的利用提供了一个有前途的解决方案，而转化率和效率却令人失望。为了应对这一挑战，首次开发了四种具有良好生物相容性的天然深共熔溶剂（NADES），并将其用作一氧化碳电酶转化中的共电解质。结果表明，与传统缓冲液相比，基于丝氨酸-甘氨酸的溶液具有较高的一氧化碳溶解度和电催化活性。通过将丝氨酸-甘氨酸应用于一氧化碳的电酶转化，产物（甲醇）的产率比在Tris-HCl缓冲液中（0.22 mM）高出两倍，比对照反应高出16倍。
