Highly Efficient CO2 Capture to a New-Style CO2-Storage Material

A highly effective and economically feasible system for capturing CO, 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.
