Stamberga et al. (2022): Synergistic direct air capture of CO2 with aqueous guanidine/amino acid solvents

Diana Stamberga, Nikki A. Thiele, Radu Custelcean IN: MRS Advances (2022),

Methylglyoxal-bis(iminoguanidine) (MGBIG) has been recently identified as a promising sorbent for direct air capture (DAC) of carbon dioxide via crystallization of guanidinium carbonate salts. In this study, the effects of aqueous amino acids and oligopeptides, such as glycine, sarcosine, serine, arginine, taurine, lysine, and glycylglycine, on the efficacy of DAC by crystallization of MGBIG carbonate have been investigated.
