Preparation method of nitrogen-doped MOF-derived nickel oxide/carbon tube hollow carbon composite material capable of being used for supercapacitor

A preparation method of a nitrogen-doped MOF-derived nickel oxide/carbon tube-coated hollow carbon composite material for a supercapacitor comprises the following steps: on the premise of adding sodium dodecyl benzene sulfonate, mixing a nickel source with pyromellitic acid and 3, 5-pyrazoledicarboxylic acid for solvothermal reaction to prepare nitrogen-doped Ni-MOFs with a hollow structure; and calcining the product in a nitrogen atmosphere, and oxidizing the product through a low-concentration H2O2 oxidation process to obtain the product. The template agent is not required to be removed in a subsequent process, the hollow structure is not required to be obtained through a post-treatment method, the method is simple and convenient, and the cost is saved; more active sites can be provided for the oxidation-reduction reaction, and sites can be provided for the growth of the carbon nanotubes; hydrogen peroxide can oxidize metal particles under mild conditions to prepare metal oxides, so that the damage of a con
