The invention provides a preparation method of a tin dioxide/two-dimensional nano titanium carbide composite material. The preparation method comprises: carrying out ball milling on ternary layered Ti3AlC2 ceramic powder; immersing the obtained product in hydrofluoric acid solution to perform the reaction for 6h to 120h; stirring, centrifugally cleaning a corrosion product by using deionized water, and drying an obtained solid sample to obtain a two-dimensional layered nano material MXene-Ti3C2; and mixing SnCl4.5H2O, glucose and the two-dimensional nano MXene-Ti3C2, using ethanol as a solvent, adjusting PH to 12 to 14, stirring with a magnetic force for 2h, performing the reaction at 120 DEG C for 6h, and after naturally cooling to a room temperature, carrying out centrifuging and drying to obtain a SnO2/MXene-Ti3C2 composite material. The material obtained by the preparation method can effectively alleviate a volume effect of SnO2 nano particles, and the SnO2/MXene-Ti3C2 nano composite material has an excel
