Abstract

The anion-exchange property of metal cation-mediated bridged hybrid mesostructured materials (MBH) prepared from functional ligands of 3-aminopropyltriethoxysilane (aptes, H₂NCH₂CH ₂CH₂Si(OEt)₃) is carefully investigated. The results of chemical element analysis, XRD, FT-IR, and TG indicate that both small anions such as CH₃COO^-, NO₃^- and large anion surfactant such as SDS^- can be exchanged into MBH. All anion sites in MBH are exchangeable, which results in a remarkable anion-exchange capacity of 3.9 mmol/g. Furthermore, MBH materials has been also prepared from chelating ligands of H₂NCH₂CH ₂HNCH₂CH₂CH₂Si(OMe)₃, and characterization of the samples show that the upgraded MBH has a better ordered hexagonal mesostructure and a higher anion-exchange capacity than conventional MBH samples.
