METHOD FOR PRODUCING ZIRCONIUM DIOXIDE NANOTUBES WITH QUANTUM CONDUCTORS Russian patent published in 2021 - IPC H03K3/38 C01G25/02 

FIELD: chemistry.

SUBSTANCE: invention relates to an electrochemical technology for producing zirconium dioxide ZrO₂ nanotubes with subsequent formation of quantum conductors. ZrO₂ nanotubes are synthesised by the method of anodising a Zr substrate in an ethylene glycol-based electrolyte with a content of 5 ±1% wt. of H₂O and 1.0 ±0.31 of NH₄F at a constant voltage in the range of 20 ±5 V and thermal regulation of the anode at a temperature of 10±5°C. A Me electrode made of gold or platinum is then applied to the ZrO₂ nanotubular layer. Quantum conductors are formed in an external electric field with a voltage of less than 25 kV/cm by grounding the Zr substrate and applying a positive voltage to the Me electrode. The amount of quantum conductors is then controlled by an electric field with a voltage of less than 6 kV/cm by grounding the Zr substrate and applying a positive voltage to the Me electrode.

EFFECT: production of quantum conductors stable at room temperature from oxygen vacancies in ZrO₂ nanotubes.
