Abstract

In this study, a novel ionic gelation (IG) of sodium tripolyphosphate (TPP) and spirulina was prepared that, supported on magnetic fibrous silica nanospheres (Fe3O4/KCC-1/IG), has been developed for the synthesis of N-[(2-hydroxyethoxy)carbonyl]glycine from carbon dioxide, ethylene oxide, and α-amino acid. This morphology ultimately leads to higher catalytic activity for the KCC-1-supported ionic gelation. The Fe3O4/KCC-1/IG MNPs were thoroughly characterized by using TEM, FESEM, VSM, FT-IR, TGA, and BET. We supported an ionic gelation on the surface of silica and used spirulina and TPP as a catalyst; the observations were exploited in the direct and selective chemical fixation of CO2 to afford high degrees of CO2 capture and conversion. © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2018.
