Abstract
The present invention discloses a preparation method of a sulfonated two-dimensional titanium carbide nanosheet, which comprises the following steps of preparing two-dimensional titanium carbide by using aluminum atomic layers in hydrofluoric acid chemical stripping layer-shaped titanium aluminum carbide; preparing sulfanilic acid diazosalt; conducting a sulfonation reaction between the two-dimensional titanium carbide and the sulfanilic acid diazosalt to prepare the sulfonated two-dimensional titanium carbide nanosheet. The sulfonated two-dimensional titanium carbide nano material prepared through the present invention has good dispersity in water and common organic solvents, and a single-layer or few-layer sulfonated two-dimensional titanium carbide nanosheet with large size and high quality can be obtained after ultrasonic treatment is performed on a dispersion liquid. The preparation method has the characteristics of low production cost, easiness in obtaining raw materials, and simplicity and controllability during preparation.
