Abstract

The invention discloses a method for preparing a graphene-like two-dimensional laminar titanium carbide nanoplate. The method comprises the following steps: preparing Ti3AlC2 powder by an in-situ hot-pressing solid-liquid reaction; preparing two-dimensional titanium carbide by a chemical liquid phase reaction; performing vacuum calcination post-treatment, and the like. The method can be used for preparing a Ti3AlC2 precursor with excellent crystallinity and high purity under simple process flow, stable process parameters, controllable process, high efficiency, low cost, short time and low pressure; the information that the transverse size of the two dimensional Ti3AlC2 nanoplate prepared by the method can be 5-10 microns, the average thickness of a single layer is about 10-20 nanometers can be found from an SEM picture, the inter-laminar spacing is remarkably enlarged after calcination treatment, and the laminar surface is regular and smooth.

Description

technical field

[0001] The invention belongs to the technical field of preparation of nanomaterials, and in particular relates to a method for synthesizing graphene-like two-dimensional layered titanium carbide nanosheets. Background technique

[0002] Since the discovery of graphene by Novoselov and Geim et al., the synthesis, performance and application of two-dimensional materials have become the most important research fields of material scientists, and a new wave of research on two-dimensional materials has been set off in the academic community. After the material structure is changed from three-dimensional to two-dimensional, it shows a unique surface structure and electronic properties, and has excellent mechanical, thermal, electrical and optical properties. For example, graphene, which can be obtained by exfoliating layered graphite with a simple micromechanical exfoliation method, has properties such as high light transmittance, high thermal conductivity, high ele...
