Carbon dioxide (CO₂) capture is an essential method for emission control. In CO₂ capture, although with the promising advantage of industrial application, chemical absorption meets the challenge of substantial energy consumption. Thus, an advanced solvent with liquid metal GaInSn/PANI/TEMPO has been first developed to reduce the energy consumption. The intensified thermoelectric effect between GaInSn/PANI/TEMPO has the potential to enhance the CO₂ desorption. Density functional theory (DFT) model and spherical mass transfer and energy transfer model in the nanoscale are developed to study the mass and energy transfer in CO₂ and GaInSn/PANI/TEMPO. The CO₂ fraction, electron density, and velocity in the nanodomain are studied. The symmetrical electron density zone is identified for the thermoelectric effect. The mass transfer coefficient is increased by twofolds. The thermoelectric conversion amount reaches 32.6–44.8% and the energy consumption is reduced to 1.07 GJ t⁻¹. The CO₂ desorption is finally proven to occur at temperature below 339 K. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.

液态金属和用于捕获 CO2 的溶剂

二氧化碳 (CO ₂ ) 捕获是排放控制的基本方法。在CO ₂捕获中，虽然具有工业应用的有前景的优势，但化学吸收遇到了大量能源消耗的挑战。因此，首先开发了一种具有液态金属 GaInSn/PANI/TEMPO 的高级溶剂以降低能耗。GaInSn/PANI/TEMPO 之间增强的热电效应有可能增强 CO ₂解吸。密度泛函理论（DFT）模型以及纳米尺度的球形传质和能量传递模型被开发用于研究CO ₂和GaInSn/PANI/TEMPO 中的质量和能量传递。二氧化碳₂研究了纳米域中的分数、电子密度和速度。对称电子密度区被确定为热电效应。传质系数增加了两倍。热电转化量达到32.6-44.8%，能耗降低到1.07 GJ t ^-1。最终证明CO ₂解吸在低于 339 K 的温度下发生。 © 2021 Society of Chemical Industry 和 John Wiley & Sons, Ltd.。
