The family of 2D materials has expanded quite rapidly, especially with the addition of transition metal carbides and nitrides called MXenes, in the last decade. Since their discovery in 2011, about 30 different MXenes have been synthesized, and the structure and properties of several dozens have been predicted by first-principles approaches. Given the outstanding advances in the MXene field, it is thus appropriate to review the most relevant properties of these MXenes and point out their potential applications. In this article, the structural, transport, magnetic, vibrational, mechanical, and electrochemical properties of MXenes are overviewed. The goal is to illustrate how the chemical versatility in the intrinsic composition and surface terminations combined with the potential addition of a fourth element enable to tune MXenes properties to meet the targeted applications.

二维MXene的物理特性：从理论上讲

在过去的十年中，二维材料家族的发展非常迅速，特别是添加了称为MXenes的过渡金属碳化物和氮化物。自2011年被发现以来，已经合成了大约30种不同的MXene，并且通过第一性原理已经预测了数十种结构和性能。鉴于MXene领域的杰出进步，因此有必要审查这些MXene的最相关属性并指出其潜在应用。本文概述了MXene的结构，传输，磁性，振动，机械和电化学性质。
