STUDY OF HIERARCHICAL STRUCTURES IN TIN DIOXIDE BASED NANOSIZED FILMS

Among a large number of physical and chemical methods for obtaining materials with various functional characteristics, one of the very interesting and simple methods is sol-gel technology. Materials synthesized using sol-gel technology have high chemical homogeneity, which is definitely a big plus. And by changing the initial environmental conditions and solution parameters, it is possible to control the size and shape of the particles obtained, as well as the pore structure of the synthesized products. At present, much attention is paid to the study of hierarchical structures based on tin dioxide. Since they are distinguished by a large surface area, stable physicochemical properties, low cost of production, environmental friendliness of the method, as well as high surface permeability and low density. This article describes the results of the synthesis of hierarchical structures in thin films based on tin dioxide. The initial solution is a lyophilic film-forming system SnCl₄/EtOH/ NH₄OH. A direct dependence of the formation of hierarchical structures on the volume of ammonium hydroxide additive was found. This helps to control the shape and size of the synthesized structures when changing the ratio of the initial precursors. And as a consequence, it allows influencing the final physical and chemical characteristics of the obtained samples for their further use as transparent conductive coatings, sensors for various gases (including toxic ones), in solar panels, etc.
