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