The invention discloses a preparation method and applications of a hairy
ball type Ti3C2(MXene)nanometer material. The preparation method comprises: adding a precursor Ti3AlC2(MAX) into HF, magnetically stirring for 72 h at a
room temperature, centrifugally washing to achieve a
neutral state, collecting precipitate, and
drying at 60 DEG C to obtain black
powder, ie., a two-dimensional Ti3C2(MXen)material; and adding the two-dimensional Ti3C2(MXene) material into a
mixed solution containing a strong alkali and H2O2, uniformly stirring, carrying out
hydrothermal treatment, centrifugally collecting precipitate, and
drying at 60 DEG C to obtain a white powdery sample, ie., the hairy
ball type Ti3C2(MXene) nanometer material. According to the invention, the prepared hairy
ball type Ti3C2(MXene) nanometer material has excellent
electrochemical energy storage performance, and the simple and easy-to-operate preparation path is provided for application of the hairy ball type Ti3C2(MXene)nano material in the field of
electrode materials such as supercapacitors,
lithium ion batteries and the like.
