Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, in particular to a method for preparing hairball-type Ti 3 C 2 (MXene) nanomaterials approach. Background technique [0002] Ti 3 C 2 (MXene) is a new type of graphene-like two-dimensional material. The rich functional groups on its surface endow it with excellent chemical reactivity and hydrophilicity. The unique structure makes it have good electrical conductivity and thermal stability, thereby increasing its energy storage. It has been widely used in electrochemical energy storage fields such as supercapacitors, lithium-ion batteries, and sodium-ion batteries, and has become a research hotspot in the fields of chemistry, physics, and materials. However, its low mass-to-capacity and easy agglomeration hinder its wider application. Therefore, how to prepare Ti with different morphologies 3 C 2 (MXene) is the prerequisite for its extensive application in the above fields. ...
