Preparation method of uniform nano-titanium carbide

The invention discloses a preparation method of uniform nano-titanium carbide, and belongs to the technical field of nano-titanium carbide. The technical problems of high costs of raw materials, big dangers and long operation periods of chemically-synthesized MXene materials and the damage to a human body caused by using hydrofluoric acid are solved; in addition, the problems of poor uniformity and non-uniformity of shapes of materials prepared by an existing method are solved. The method disclosed by the invention comprises the steps: 1, putting foamed nickel on a graphite block, putting the foamed nickel and the graphite block together in a quartz tube of a chemical vapor deposition furnace, heating, turning off an air outlet valve after the temperature reaches the set temperature and turning on a vacuum pump at the same time; 2, simultaneously and uniformly introducing an ethanol solution dissolved with titanium chloride and an ethanol solution dissolved with aluminum chloride; 3, turning off the vacuum pu
