摘要
离子液体(IL)和深共晶溶剂(DES)具有电化学稳定性窗口宽、挥发性低和二氧化碳溶解度高等特点,因此在二氧化碳的反应捕集与转化(RCC)方面具有巨大的潜力。利用电气化和模块化工艺直接利用捕获的二氧化碳,无需热再生或压力再生步骤来浓缩二氧化碳,从而消除了压缩、运输或储存气体的需要,这在环境和经济方面都很有意义。使用水性电解质进行二氧化碳的传统电化学转化过程中,二氧化碳的溶解度有限,且需要较高的能量才能生产出与工业相关的产品。此外,水性系统具有竞争性氢进化。在过去的十年中,ILs 和 DESs 及其复合材料的设计取得了重大进展,可以从稀释气流中分离出 CO2。与此同时,但不一定是协同作用的研究也集中在少数几种用于电化学还原 CO2 的 IL 和 DES 上,通常使用水性或非水性溶剂对其进行稀释。由此产生的电解质-电解质界面呈现出 RCC 的复杂形态。在本综述中,我们将介绍如何针对 RCC 对 IL 和 DES 进行调整,并特别讨论二氧化碳的化学吸附和电还原机制。在 RCC 的背景下讨论了 ILs 和 DESs 的关键块体和界面特性,并通过技术经济评价介绍了这些电解质的潜力。
Reactive capture and electrochemical conversion of CO2 with ionic liquids and deep eutectic solvents.
Ionic liquids (ILs) and deep eutectic solvents (DESs) have tremendous potential for reactive capture and conversion (RCC) of CO2 due to their wide electrochemical stability window, low volatility, and high CO2 solubility. There is environmental and economic interest in the direct utilization of the captured CO2 using electrified and modular processes that forgo the thermal- or pressure-swing regeneration steps to concentrate CO2, eliminating the need to compress, transport, or store the gas. The conventional electrochemical conversion of CO2 with aqueous electrolytes presents limited CO2 solubility and high energy requirement to achieve industrially relevant products. Additionally, aqueous systems have competitive hydrogen evolution. In the past decade, there has been significant progress toward the design of ILs and DESs, and their composites to separate CO2 from dilute streams. In parallel, but not necessarily in synergy, there have been studies focused on a few select ILs and DESs for electrochemical reduction of CO2, often diluting them with aqueous or non-aqueous solvents. The resulting electrode-electrolyte interfaces present a complex speciation for RCC. In this review, we describe how the ILs and DESs are tuned for RCC and specifically address the CO2 chemisorption and electroreduction mechanisms. Critical bulk and interfacial properties of ILs and DESs are discussed in the context of RCC, and the potential of these electrolytes are presented through a techno-economic evaluation.
