1. A preparation method of a transition metal oxide nano material is characterized by comprising the following steps:

  • adding ionic liquid and transition metal salt into a reaction kettle, heating under a protective atmosphere for reaction, then carrying out solid-liquid separation, washing the obtained solid, drying and roasting to obtain a transition metal oxide nano material;

    the ionic liquid is HmimBF4

    The transition metal salt is any one of nitrate, acetate or oxalate of transition metal or a mixture of at least two of the nitrate, acetate or oxalate of the transition metal;

    the transition metal in the transition metal salt is any one or combination of at least two of chromium, manganese, zinc, cobalt, nickel or copper;

    heating when the gauge pressure of the protective atmosphere is 1 kPa;

    the mass ratio of the ionic liquid to the transition metal salt is 25-88;

    1;

    the reaction temperature is 180-250 ℃

    , the reaction time is 0-10 h, not including 0, and the obtained transition metal oxide nanoparticles are spherical.
