| Abstract: | A new CO2 fixation process into solid CO2‐storage materials (CO2SMs) under mild conditions has been developed. The novel application of amine–glycol systems to the capture, storage, and utilization of CO2 with readily available 1,2‐ethanediamine (EDA) and ethylene glycol derivatives (EGs) was demonstrated. Typically, the CO2SMs were isolated in 28.9–47.5 % yields, followed by extensive characterization using 13C NMR, XRD, and FTIR. We found that especially the resulting poly‐ethylene‐glycol‐300‐based CO2SM (PCO2SM) product could be processed into stable tablets for CO2 storage; the aqueous PCO2SM solution exhibited remarkable CO2 capturing and releasing capabilities after multiple cycles. Most importantly, the EDA and PEG 300 released from PCO2SM were found to act as facilitative surfactants for the multiple preparation of CaCO3 microparticles with nano‐layer structure. |
