Abstract

The disclosure provides an MAX phase material, a preparation method therefor, and application thereof. The molecular formula of the MAX phase material is represented as Mn+1(AzA′1−z)hXn, wherein M is selected from group IIIB, IVB, VB or VIB elements, A is selected from element Zn, Cu, Ni, Co, Fe or Mn, A′ is selected from group IB, IIB, VIII, IVA, VA or VIA elements, X is selected from elements C and/or N, n is 1, 2, 3 or 4, 0<z≤1, a unit cell of the MAX phase material is formed by alternately stacking Mn+1Xn units and (AzAzA′1−z)h layers of atoms, and h is the number of layers of the (AzAzA′1−z) layers of atoms located between the Mn+1Xn unit layers, and h is 1, 2 or 3.
