Аннотация:Anatase-mordenite nanocomposite was synthesized in situ and characterized by X-ray diffraction analysis, Brunauer-Emmett-Teller measurements, infrared (IR) spectroscopy, electron diffraction measurements, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and scanning and transmission electron microscopy. It was found that X-ray-amorphous anatase located in the zeolite micropores resulted in a decrease in the specific surface of anatase-mordenite comparedto the initial mordenite. Anatase-containing nanoparticles in anatase-mordenite showed round shape and formed nano-associates and conglomerates. The water content in the zeolite cavities in anatase-mordenite was lower comparedto mordenite. Anatase-mordenite nanocomposite exhibited higher photocatalytic activity in the model decomposition reaction of methyl orange under ultraviolet (UV) radiation and higher adsorption capacity for extraction of P(V) and As(V) ions from aqueous environment in the dark comparedto the initial mordenite or anatase due to an increase in the content of active OH-groups on the nanocomposite surface comparedto mordenite and an increase in the specific surface comparedto anatase.
