1. the preparation method of a cobaltosic oxide nano cage is characterized in that, comprising:

  • The cobalt potassium cyanate and the polyvinylpyrrolidone of scheduled volume is soluble in water, obtain cobalt potassium cyanate and polyvinylpyrrolidonesolution solution;

    Under predetermined temperature, the cobalt acetate drips of solution is added in said cobalt potassium cyanate and the polyvinylpyrrolidonesolution solution, leave standstill the scheduled time through after the magnetic agitation, obtain cobalt cyanic acid cobalt through centrifugation again;

    Dried said cobalt cyanic acid cobalt is calcined the scheduled time in air, and calcining heat is respectively 400 ℃

    , 450 ℃ and

    550 ℃

    , and the calcining back obtains the cobaltosic oxide nano cage.Dried said cobalt cyanic acid cobalt is calcined the scheduled time in air, and calcining heat is 650 ℃

    , and the calcining back obtains the mixture of cobaltosic oxide nano cage and the solid nano particle of cobaltosic oxide.
