Medium-entropy MAX phase material, medium-entropy two-dimensional material and preparation method of medium-entropy MAX phase material
The invention discloses a medium-entropy MAX phase material, a medium-entropy two-dimensional material and a preparation method thereof, wherein the chemical general formula of the medium-entropy MAX phase material is Mn + 1AXn, and the medium-entropy MAX phase material is characterized in that an M element is selected from three or four transition metal elements and lanthanide elements; the M element contains at least two transition metal elements or lanthanide elements capable of forming a solid solution; the A element is selected from at least one of VIIB, VIII, IB, IIB, IIIA, IVA, VA and VIA family elements; the X is at least one of carbon, nitrogen, boron or oxygen, and n is 1, 2, 3, 4, 5 or 6. A medium-entropy two-dimensional material can be obtained after the component A in the medium-entropy MAX phase material is etched. In the invention, the medium-entropy MAX phase material and the medium-entropy two-dimensional material which can stably exist in a single phase are prepared by introducing the multi-component transition metal capable of achieving solid solution, inducing the structure to generate lattice distortion and optimizing the electronic structure.
