Nitrogen-containing medium-entropy or high-entropy MAX phase material and preparation method and application thereof
The invention discloses a preparation method of a nitrogen-containing medium-entropy or high-entropy MAX phase material and a two-dimensional material. The preparation method comprises the following steps of reacting at least one nitrogen-containing MAX phase and a plurality of nitrogen-free MAX phases serving as raw materials, wherein the sum of element types of M in the MAX phase is more than four, and a nitrogen-containing medium-entropy or high-entropy MAX phase material is obtained, or taking at least one nitrogen-containing MAX phase, simple substances or compounds of a plurality of transition metals and simple substances or compounds of A as raw materials for reaction, enabling the sum of element types of M and element types of a plurality of transition metals in the MAX phase to be more than four, and preparing the nitrogen-containing medium-entropy or high-entropy MAX phase material. The method is simple in process and easy for industrial enlarged production, and lays a foundation for application of nitrogen-containing medium-entropy or high-entropy MAX phase materials and two-dimensional materials.
本发明公开了一种含氮中熵或高熵MAX相材料及二维材料的制备方法，包括步骤：以至少一种含氮的MAX相和数种不含氮的MAX相作为原料进行反应；其中，MAX相中的M的元素种类之和为四种以上，得到含氮中熵或高熵MAX相材料；或，以至少一种含氮的MAX相、数种过渡金属的单质或化合物和A的单质或化合物作为原料进行反应，MAX相中M的元素种类与数种过渡金属的元素种类之和为四种以上，制备得到含氮中熵或高熵MAX相材料。本发明工艺简单，易于工业化放大生产，为含氮中熵或高熵MAX相材料及二维材料的应用奠定基础。
