摘要（英）：

The invention relates to an N-doped TiO2/MXene composite material and preparation method and application thereof, and belongs to the technical field of a nanometer material. The preparation method comprises the steps of preparing an MXene material and preparing the N-doped TiO2/MXene composite material by taking the MXene material and hexamethylene tetramine as raw materials by a hydrothermal method. The MXene in the composite material is of a two-dimensional layered structure, TiO2 nanoparticles are distributed between MXene material layers and in surfaces of the MXene material layers, an NH<4+> ion insertion layer is arranged between the MXene material layers, and N atoms are doped in the MXene. When used for fabricating a supercapacitor electrode, the composite material has favorable conductivity and also has relatively high specific capacity and stable charge-discharge cycle property. The preparation method of the composite material is simple, is low in cost and is suitable for industrial production.
