Application

Vanadium(III) oxide (V2O3) can be used for a variety of sustainable applications such as:
  • anode material for the fabrication of lithium-ion batteries[1]
  • fabrication of vanadium redox flow batteries[2]
  • preparation of vanadium nitride (VN) for potential usage in hydrodenitrogenation (HDN), and hydrodeoxygenation (HDO)[3]
