FIELD: technological processes.
SUBSTANCE: invention relates to methods for forming a porous oxide material and can be used to develop anode materials for lithium-ion batteries and supercapacitors of a new generation, sensitive elements of gas sensors. Method for producing films of porous crystalline tin dioxide involves creating a composite based on a matrix, as used for layers of multi-walled carbon nanotubes (MWCNT). Composite is formed by magnetron deposition on a matrix of non-stoichiometric amorphous tin oxide (MWCNT/SnOx). Then the removal of the matrix is carried out by heat treatment in air at a temperature of 400-700 °C for 15–45 minutes.
EFFECT: invention makes it possible to increase the purity of films of porous crystalline tin dioxide, in which no undesirable impurities are present.
