Fe(III) Containing MCM-48 Type Mesoporous Molecular Sieves with Framework Zeolite Secondary Building Units
Abstract:Fe(III) containing mesoporous materials (FeMMSH) with zeolite building units were first time synthesized. XRD and N2 adsorption/desorption analysis confirm the mesoporous characters similar to MCM-48. FT-IR analysis of FeMMSH showed an additional band at about 530–550 cm− 1, characteristic of double five-membered ring of zeolite (ZSM-5) secondary building unit. The Fe(III) in FeMMSH materials is present in tetrahedral, and distorted tetrahedral framework are evident from EPR and DRUV-VIS spectra.
