METHOD OF OBTAINING FILMS OF POROUS CRYSTALLINE TIN DIOXIDE Russian patent published in 2018 - IPC C01G19/02 B82B3/00 B82Y30/00 C23C14/08 C23C14/35 C01B32/174

Abstract RU 2671361 C1

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/SnO_x). 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.
