Abstract
The present invention discloses a selenium-doped MXene material and a preparation method thereof, comprising the following steps: (1) adding MXene and an organic selenium source into a dispersant, and stirring to prepare a dispersion with a concentration of 10 mg/ml to 100 mg/ml, wherein a mass ratio of MXene and an organic selenium source is 0.1 to 1:1; (2) transferring the dispersion into a reaction kettle, heating to 110° C. to 230° C., reacting for 10 h to 30 h, and then naturally cooling to a room temperature; and (3) washing the product obtained in the step (2) with a cleaning agent, centrifuging to collect a precipitate, and drying the precipitate under vacuum to obtain the selenium-doped MXene material. The composite material prepared by the present invention has high specific surface area, good electrical conductivity, cycle stability performance, rate performance and high theoretical specific capacity.
