The invention relates to a method for preparing an MXene/carbon nanotube composite material, which comprises the following steps: carrying out etching reaction on MAX-phase ceramic powder in a mixed solution of nickel chloride and hydrochloric acid, and cleaning and drying the reaction product to obtain MXene attached with nickel salt; putting the obtained MXene attached with the nickel salt intoa reactor, conducting vacuumizing, introducing inert gas, and introducing reducing gas at a certain temperature to reduce the nickel salt into nickel metal particles; and introducing a carbon source gas into the MXene with the nickel metal particles on the surface at a certain temperature, and carrying out catalytic cracking on the carbon source under the catalytic action of the nickel metal particles on the surface of the MXene to generate carbon nanotubes, thereby obtaining the MXene/carbon nanotube composite material. 本发明涉及一种制备MXene/碳纳米管复合材料的方法，所述方法包括：将MAX相陶瓷粉体在氯化镍和盐酸的混合溶液中进行刻蚀反应，然后将反应产物进行清洗、干燥得到附着镍盐的MXene；将所得的附着镍盐
