Abstract:
The room-temperature synthesis of a new two-dimensional (2D) zirconium-containing carbide, Zr3C2T(z) MXene is presented. In contrast to traditional preparation of MXene, the layered ternary Zr3Al3C5 material instead of MAX phases is used as source under hydrofluoric acid treatment. The structural, mechanical, and electronic properties of the synthesized 2D carbide are investigated, combined with first-principles density functional calculations. A comparative study on the structrual stability of our obtained 2D Zr3C2T(z) and Ti3C2T(z) MXenes at elevated temperatures is performed. The obtained 2D Zr3C2T(z) exhibits relatively better ability to maintain 2D nature and strucural integrity compared to Ti-based Mxene. The difference in structural stability under high temperature condition is explained by a theoretical investigation on binding energy.
