FIELD: chemistry.
SUBSTANCE: invention can be used in producing heterogeneous catalysts with highly developed surface, and electrodes in lithium-ion batteries. Electrochemical method for producing nano-sized titanium (IV) oxide structures involves anodic oxidation of titanium electrode in ionic liquid with addition of water or propylene glycol in an air atmosphere. Ionic liquid has general formula K+A-, where K+ - alkylimideazoline, A- -NTf2 -, or PF6 -, or Cl-. Anodic oxidation is carried out at 20-25 °C for 5-30 minutes at direct current of 1-10 mA or at constant potential of 1-10 V.
EFFECT: invention enables to obtain titanium oxide nanoparticles in the form of nanospheres, nanofibres or nanorods depending on conditions of synthesis.
