以1，2-乙二胺（EDA）+聚乙二醇300（PEG）为原料，开发了一种高效、经济的CO2捕集体系，在温和条件下将CO2活化并直接转化为新型固体CO2储存材料（CO2 SM）。CO2 SM的本质是烷基碳酸盐，其潜在的应用是利用元素氮促进植物生长。此外，EDA + PEG水溶液可以多次循环使用，而不会显著损失其捕获和释放CO2的能力。因此，该工艺为CO2的综合利用提供了另一种途径，并可能使CO2转化为具有附加值的化学品。
A highly effective and economically feasible system for capturing CO2 was developed from 1,2-ethanediamine (EDA) + polyethylene glycol 300 (PEG), in which CO2 was activated and directly transformed to a novel solid CO2 storage material (CO2SM) under mild conditions. The essence of CO2SM is alkylcarbonate salt, and the potential applications of CO2SM would take advantage of elemental nitrogen to boost the growth of plants.. In addition, the EDA + PEG aqueous solution could be recycled multiple times without significant loss in its ability to capture and release CO2. Thus, the process offered an alternative way for comprehensive utilization of CO2 and potentially enables the CO2 conversion to a value-added chemical.
