Description

technical field [0001] The invention relates to the technical field of MXene materials, in particular to a novel MXene metal nanocomposite material, a preparation method and an application. Background technique [0002] As a new type of nanomaterial, MXene has been closely watched by researchers since its discovery in 2011. The preparation of MXene materials is mainly obtained by etching MAX phase raw materials. MXene materials have high electrical conductivity, large specific surface area, and good mechanical properties. At the same time, they also have a certain self-reduction ability on the surface. Therefore, MXene materials are widely used in catalysis, energy storage, electromagnetic shielding, and electrical devices. [0003] For example, the Chinese patent application (publication number is CN110841721A) discloses MXene two-dimensional materials, Cu / MXene catalysts and their preparation methods and applications, which make a uniform mixed reaction system containing ...
