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
在这项研究中,制备了一种新的三聚磷酸钠(TPP)和螺旋藻的离子凝胶(IG),并在磁性纤维二氧化硅纳米球(Fe 3 O 4 / KCC-1 / IG)上负载了该化合物,用于合成N -[[(2-羟基乙氧基)羰基]甘氨酸,来自二氧化碳,环氧乙烷和α-氨基酸。这种形态最终导致对KCC-1负载的离子胶凝反应具有更高的催化活性。通过使用TEM,FESEM,VSM,FT-IR,TGA和BET对Fe 3 O 4 / KCC-1 / IG MNP进行了全面表征。我们支持在二氧化硅表面进行离子凝胶化,并使用螺旋藻和TPP作为催化剂。这些观察结果被用于直接和选择性化学固定CO 2的过程中提供高度的CO 2捕获和转化。
