Provided are nitrogen-doped hollow cobaltosic oxide, and a preparation method therefor and the use thereof. The nitrogen-doped hollow cobaltosic oxide has a chemical formula of Co3O4-COF-T-D@C-N, wherein COF-T-D is a covalent organic framework. The preparation method therefor comprises the following steps: (1) mixing an adamantane containing an amino group, a naphthalene containing an aldehyde group and a hydroxyl group, and a cosolvent, adding an acidizing fluid for acidification, and performing a heating reaction to obtain a first solid COF-T-D; (2) adding the first solid COF-T-D to an organic solvent and mixing and stirring same with a cobalt salt, performing a reaction, the subjecting same to solid-liquid separation, and taking a solid phase to obtain a second solid Co-COF-T-D; and (3) cleaning the second solid Co-COF-T-D, adding nitrogen, subjecting same to a heat treatment, cooling same, and adding oxygen for oxygenation to obtain the nitrogen-doped hollow cobaltosic oxide Co3O4-COF-T-D@C-N.
