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.
