High-entropy two-dimensional material, high-entropy MAX phase material and preparation methods thereof
The invention discloses a high-entropy two-dimensional material, a high-entropy MAX-phase material and preparation methods thereof. The high-entropy two-dimensional material is of a two-dimensional lamellar structure and is composed of an element M and an element X, the element M is selected from at least five metal elements of IIIB, IVB, VB, VIB, VIIB, VIII, IB and IIB, and the element X is selected from at least one non-metal element of IIIA, IVA, VA and VIA. The chemical general formula of the high-entropy MAX phase material is Mn+1AXn, the high-entropy MAX phase material can serve as a precursor for preparing a high-entropy two-dimensional material, the high-entropy two-dimensional material is obtained by etching a component A in the high-entropy MAX phase material, the high-entropy two-dimensional material has an ultrathin two-dimensional lamellar structure, meanwhile, a large number of metal atoms are exposed on the surface, and therefore the two-dimensional material is endowed with new performance.
本发明公开了一种高熵二维材料、高熵MAX相材料及其制备方法，其中，高熵二维材料具有二维片层结构，由M元素和X元素组成，其中，所述M元素选自IIIB、IVB、VB、VIB、VIIB、VIII、IB、IIB族中的至少五种金属元素，X元素选自IIIA、IVA、VA和VIA中的至少一种非金属元素；高熵MAX相材料的化学通式为Mn+1AXn，能够作为制备高熵二维材料前躯体，通过刻蚀其中的A组分得到高熵二维材料，本发明的高熵二维材料具有超薄的二维片层结构，同时表面具有大量的金属原子暴露，从而赋予二维材料新的性能。
