A new class of two-dimensional (2D) materials known as MXene became one of the most promising candidates under investigation after the discovery of the first member of this group, Ti₃C₂T_x, in 2011. These layered transition metal nitrides, carbonitrides, and carbides have offered an attractive new area in inorganic 2D materials with their fascinating structural and chemical characteristics due to the versatility in elemental compositions and surface terminations. Significantly, the surface hydrophilicity of MXenes facilitates the easy composite formation with carbonaceous materials, polymers, and metal oxides that further opens up an efficient pathway for tuning the characteristics of MXenes for different applications. Despite exponentially increasing interest, MXenes lack proper systematic information. This article is focused on reviewing the most applicable aspects of MXenes including structural features with their relevant characteristics and applicability by describing both experimental and theoretical perspectives. A critical survey on current trends, status, and possibilities of MXenes and MXene-based materials have been represented for energy-related applications as well as electromagnetic interference (EMI) shielding, blends and composites, sensors, organic light-emitting diodes (OLED), and actuators and robotics associated with the limitations and future potentialities.

MXene 研究的当前趋势：特性和应用

在发现该组的第一个成员 Ti ₃ C ₂ T _x后，一类称为 MXene 的新型二维 (2D) 材料成为正在研究的最有希望的候选材料之一, 在 2011 年。由于元素组成和表面终止的多功能性，这些层状过渡金属氮化物、碳氮化物和碳化物以其迷人的结构和化学特性为无机二维材料提供了一个有吸引力的新领域。重要的是，MXenes 的表面亲水性促进了与含碳材料、聚合物和金属氧化物的轻松复合，这进一步开辟了一条有效途径来调整 MXenes 在不同应用中的特性。尽管兴趣呈指数增长，但 MXenes 缺乏适当的系统信息。本文侧重于通过描述实验和理论观点来回顾 MXenes 最适用的方面，包括结构特征及其相关特征和适用性。
