The invention relates to a method for intercalating and stripping a two-dimensional crystal titanium carbide nano material by using ammonia water. The method comprises the following steps: putting a two-dimensional crystal titanium carbide material into ammonia water, performing intercalation and stripping by using a high-speed shearing machine, and performing washing and vacuum drying, thereby obtaining the two-dimensional crystal titanium carbide nano material of which the interlayer spacing is increased. The two-dimensional crystal titanium carbide nano material provided by the invention is relatively large in interlayer spacing, the aggregation effect of titanium carbide can be overcome to a certain extent, the specific surface area of the two-dimensional crystal titanium carbide nano material can be increased, and the properties of the material in fields of supercapacitors, lithium ion batteries, adsorption and the like can be improved.
