crystal size in the range from 30 to 5000 nm have been developed. Uniform zeolite nanocrystals were used as initial blocks for building hierarchical zeolites, the texture of material depending on the size and packing of nanocrystals. Monodisperse polystyrene microspheres (150–1100 nm) were produced as templates. Meso/macroporous Fe-silicalite materials were synthesized in PS matrix followed by the template removal via calcination. The synthesized samples were characterized by laser diffraction analysis, dynamic light scattering, X-ray diffraction, scanning and transmission electron microscopy, argon and nitrogen adsorption measurements, inductively coupled plasma optical emission spectrometry, UV visible diffuse reflectance spectroscopy and temperature-programmed desorption of ammonia. All zeolite samples exhibited high crystallinity, high BET surface area (480–650 m2/g), external surface area (180 350 m2/g) and total pore volume (0.50–0.75 cm3/g). Catalytic performance of hierarchically porous Fe-silicalite materials was studied in total liquid-phase oxidation organic molecules, including phenol, antibiotic – clarithromycin lactobionate and metal ion complexing agent – ethylenediaminetetraacetate (EDTA) by H2O2 at low temperatures (298 323 K) compared with the reference Fe-silicalite microcrystals. Hierarchical Fe-silicalites were shown to be more efficient catalysts vs Fe-silicalite microcrystals due to increasing catalytic sites accessibility. A new method of radiocobalt removal from EDTA chelates by catalytic oxidation of EDTA by H2O2 via heterogeneous Fenton-type zeolite catalysts have been suggested and patented.
