In this study, an innovative approach for the selective absorption of carbon dioxide (CO 2 ) by ionic liquid electrospray was proposed. First, the fluid dynamical characteristics of ionic liquid electrospray with 1-ethyl-3-methylimidazolium acetate in ambient air was clarified by high-speed imaging and aerosol analysis. This was followed by enhancement of CO 2 absorption by ionic liquid electrospray in a closed chamber filled with CO 2 which was successfully demonstrated for the first time. The ionic liquid electrospray drastically improves CO 2 chemisorption by achieving higher CO 2 loading ratio of ionic liquid due to the continuous generation of nano-sized droplets with a large specific surface area, as well as the sufficient spreading of the spray by the Coulomb repulsion between charged droplets.

离子液体电喷雾改善对CO 2的吸收

在这项研究中，提出了一种通过离子液体电喷雾选择性吸收二氧化碳（CO 2）的创新方法。首先，通过高速成像和气溶胶分析阐明了乙酸1-乙基-3-甲基咪唑鎓离子液体电喷雾在环境空气中的流体动力学特性。随后，在充满CO 2的密闭室内通过离子液体电喷雾增强了对CO 2的吸收，这是首次成功证明。离子液体通过连续产生具有大比表面积的纳米尺寸液滴，以及通过介于两者之间的库仑排斥力使喷雾充分散布，可通过实现更高的离子液体CO 2负载比来大幅提高CO 2化学吸附。带电的液滴。
