- Аннотация: Nanocrystalline tin dioxide SnO2 is of considerable interest for the creation of solar cells, solid-state chemical sensors, and oxidation catalysts. High adsorption properties and reactivity of nanocrystalline SnO2 are due to high concentration of surface adsorption centers, especially the coordinately unsaturated tin cations Sn4c, Sn5c, chemisorbed oxygen, and oxygen vacancies VO. In the recent years, many works have been devoted to the development of various approaches to the synthesis of nanocrystalline SnO2 and to the investigation of its reactivity. The main direction of research of nanocrystalline SnO2 is aimed at increasing the selectivity of adsorption and promoting chemical reactions on the surface. The selectivity of the chemical properties of nanocrystalline SnO2 can be achieved by tuning the type and concentration of surface active centers by bulk doping immobilization of modifiers: nanoparticles based on noble metals or transition elements oxides. The data on the effect of catalytic modifiers on the composition, microstructure, type and concentration of active sites, and reactivity of nanocrystalline SnO2 are systematized in this section.
