英文摘要: Considering the perspective of sustainable development, non-biological CO2 mineralization was an important strategic significance for CO2 capture and utilization. We herein demonstrate the direct fixation of CO2 to prepare well-defined metal carbonate (MCO3, M = Ca, Sr, Ba, Mn, Cd, and Pb) crystals under mild conditions on the basis of amine-mediated chemistry. Six well-defined MCO3 crystals were successfully synthesized by regulating key influencing parameters, including the amine adding amount, CO2 pressure, reaction temperature and time, and M2+ concentration. The tested amines, including ethylenediamine (EDA), monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA), N-methyldiethanolamine (MDEA), 2-amino-2-methyl-1-propanol (AMP), and ammonium hydroxide (NH3·H2O), can buffer the pH value of the reaction solution, coordinate with the metal ion through chelation, activate the incoming CO2, and direct the growth and assembly of the MCO3 crystals. This methodology was found to be generally applicable and customizable. As a result, this study provided scientific basis for the development of amine chemistry, and such an approach was facile and potential importance for direct non-biological CO2 mineralization and well-controlled MCO3 crystals. © 2018 Elsevier Ltd Citation statistics:
