| 摘要: 在温和条件下，发展了一种以丁二醇-乙二胺体系新颖、高效地固定CO2的方法。在此方法中，CO2被快速激活并转化为一种固态的CO2储集材料（CO2SM），通过XPS、XRD、FTIR和13C NMR等技术表征证实为烷基碳酸胺。基于TGA结果，CO2SM的水溶液可以与Ca（OH）2和Ba（OH）2反应制备CaCO3和BaCO3微粒，还可用于循环吸收和解吸CO2的过程。此外，丁二醇-乙二胺水溶液在20 ℃下吸收CO2并在98.6 ℃下解吸CO2，没有明显的溶液损失。因此，丁二醇-乙二胺体系提供了一种绿色、高效、低成本的二氧化碳捕集利用方法。 |

| Abstract: A novel and high effective way to fix CO2 agilely through the system 1,4-butanediol (BDO)+1,2-ethylenediamine (EDA) under mild condition was developed. In this process, the bubbling CO2 could be activated efficiently and directly converted into a novel solid CO2-storage material (CO2SM), which was extensively confirmed as an alkylcarbonate salt using XPS, XRD, FTIR and 13C NMR analyses. As a material, the aqueous CO2SM solution could be used to prepare controllable morphologies CaCO3 and BaCO3 micro-particles by reacting with Ca(OH)2 and Ba(OH)2 according to thermogravimetry analysis (TGA) result. Additionally, the aqueous BDO+EDA system could be recycled multiple times without any important loss of CO2 capturing and releasing capability at absorption temperature of 20 ℃ and desorption temperature of 98.6 ℃. As a result, the combination of BDO+EDA seems to provide a green CO2 capture and utilization (CCU) approach featuring high efficiency and low cost. |
