Реферат: Series of hierarchical Fe-silicalites were prepared by two approaches: template synthesis and patterning Fe-silicalite nanocrystals. The synthesized samples were characterized by a number of methods: laser diffraction analysis, X-ray diffraction, scanning and transmission electron microscopy, energy-dispersive X-ray spectroscopy, argon and nitrogen adsorption measurements, inductively coupled plasma optical emission spectrometry, UV visible diffuse reflectance spectroscopy and temperature-programmed desorption of ammonia. Hierarchically porous Fe-silicalites were tested in total liquid phase catalytic oxidation of different organic molecules, including phenol, the natural polymer – lignin, macrolide antibiotic – clarithromycin lactobionate and metal ion complexing agent – EDTA by H2O2 at low temperatures (298-323 K) compared with Fe-silicalite microspheres and homogeneous Fenton reagent. Performances of hierarchical Fe-silicalites in oxidation of large organic molecules by hydrogen peroxide were significantly improved vs. the reference Fe-silicalite microbeads, resulted from increasing catalytic sites accessibility.
