摘要: Abstract Carbon mineralization into calcium carbonate (CaCO3) has been widely studied as a promising CO2 resource utilization pathway. In this work, was fixed to alkylcarbonate through phase change absorption in polyethylene glycol 200 (PEG) plus ethanediamine (EDA) system at ambient conditions. This identified by FTIR and 13C cross-polarization magic-angle spinning (CP-MAS) NMR spectra. It used both CO32− source crystal modifier induce crystallization of CaCO3 particles. The microsphere with uniform morphology vaterite acquired adjusting quality alkylcarbonate, concentration Ca2+ concentration, period without any additives. Furthermore, plausible self-assembly formation mechanism toward inducing also proposed. synthesis strategy is environmentally friendly offers an alternative for indirect CO2.
