HYBRID NANOCOMPOSITE FUNCTIONAL MATERIAL NaTiO -α-FeO Russian patent published in 2024 - IPC C01G23/00 B82Y40/00 C01G49/06 

FIELD: chemical engineering.

SUBSTANCE: hybrid nanocomposite material consisting of Na₂Ti₃O₇ nanotubes andα-phase Fe₂O₃, which is obtained by hydrothermal synthesis at a temperature of 130°C for 20 hours from a TiO₂ dispersion in a 10 M aqueous solution of NaOH with the addition of 40-400 mg FeCl₃ under ultrasonic influence for 10 minutes⋅ 6H₂O, and after cooling and washing, annealing is carried out at 400°C for 3 hours in an argon atmosphere.

EFFECT: development of energy-intensive hybrid nanomaterial Na₂Ti₃O₇ –α-Fe₂O₃ with a hierarchical two-level organization structure for use as an anode material for sodium-ion batteries, which is obtained from non-toxic substances in one stage.
