Essay

The dissertation is devoted to the research of the influence of mechanochemical, microwave and ultrasonic treatments on the physicochemical properties of tin dioxide, including their stability at high temperatures and the research of activity of the obtained samples in the processes of photodestruction of organic pollutants in aqueous solutions under visible light, as well as their sorption properties in relation to ions U(VI). The relationship between physicochemical and photocatalytic and sorption characteristics of tin dioxide is scientifically substantiated. According to DTA-TG data, the precipited and high-dispersed commercial samples correspond to composition SnO(OH)2, the low-dispersed – SnO2. The mechanochemical and microwave treatment of samples leads to partial removal of OH-groups. It`s accompanied by transformation of initial SnO(OH)2 into SnO2. Chemical composition of SnO2 doesn`t change under modification. According to XRD data, laboratory precipited samples have X-ray amorphous structure and commercial powders are crystalline. The crystal structure is partially destroyed after mechanochemical treatment but, on the contrary, improved as a result of microwave treatment. It`s shown that mechanochemical and microwave modification of precipitated and commercial SnO2 samples allows to obtain meso- and mesomacroporous materials. Peculiarity of milling in water is formation of the secondary porosity that presented by macropores. A uniform mesoporous structure is formed as a result of the MWT of wet gels and dry xerogels. UV-Vis spectra show batochromic shift of absorption edge and corresponding narrowing of band gap for modified SnO2 samples from 4.2 to 3.5-3.9 eV. It was found that when doping with highly crystalline oxides, a separate dopant phase is formed, and when doping with metal salts followed by heat treatment, only the crystalline phase of tin dioxide is preserved. When TiO(OH)2 is used as a dopant, the formation of a solid substitution solution based on SnO2 is observed. When wet SnO2 gels are doped, high values of the specific surface, increase the total volume of pores, formation of additional meso- and macropores are observed. Also, the introduction of dopants into the structure of tin dioxide contributes to the narrowing of the band gap, but to a different extent. Silver doping maximally narrows the band gap to 2.59 eV. All types of modification lead to improved functional characteristics of the obtained SnO2 samples. Mechanochemical and microwave treatment leads to the increased of photocatalytic activity of SnO2 samples in the range of visible light in the processes of photodegradation of dyes and phenols. Doping with all studied metals also contributes to an even greater increase in the photocatalytic activity of tin dioxide. On the basis of the obtained results, a simple method for producing sonochemically doped tin dioxide, active under the action of visible light, with optimal physicochemical characteristics is presented. The decisive influence of the meso- and meso-macroporous structure of tin dioxide on its sorption properties in relation to U(VI) in both cationic and anionic forms was established. Keywords: tin dioxide, mechanochemical, ultrasonic and microwave treatment, doping, porous structure, crystal structure, optical characteristics, surface structure, thermal stability, photocatalytic activity, ion exchange properties.
