Fe-silicalite nano- and microcrystals as heterogeneous Fenton-type catalysts have been synthesizedand characterized by dynamic light scattering, X-ray diffraction, scanning and transmission electronmicroscopy, nitrogen adsorption measurements, inductively coupled plasma optical emission spectrom-etry, UV visible diffuse reflectance spectroscopy and temperature-programmed desorption of ammonia.Catalytic performance of Fe-silicalites was studied in mineralization of EDTA by H2O2at 303–353 K and60Co removal from EDTA chelates. The effect of activation by the acid treatment on the state of active sites,catalytic activity and stability of Fe-silicalites was studied. Fe-silicalites nanocrystals are more efficientcatalysts vs. microcrystals due to enhanced catalytic sites accessibility.
