The progress of two-dimensional (2D) MXene-derived QDs (MQDs) is in the early stages, but the materials have aroused great interest due to their high electrical conductivity, abundant active catalytic sites, easily tunable structure, satisfactory dispersibility, remarkable optical properties, good biocompatibility, manifold functionalizations, and so on. However, up to now, there is still no review paper on MQDs. Herein, the research advances of MQDs, including their synthetic routes (top-down and bottom-up methods), properties (structural, electronic, optical and magnetic properties), functionalizations (surface modifications, heteroatom doping and the construction of composites) and applications (sensing, biomedical, catalysis, energy storage and optoelectronic devices etc.), are critically highlighted, and the future prospects and challenges of MQDs are discussed. This review will serve as a one-stop point for comprehending the most advanced developments of MQDs, and will hopefully enlighten researchers to employ MQDs for satisfying the growing requirements of the diverse applications.

二维过渡金属碳化物和氮化物（MXene）衍生的量子点（QD）：合成，性质，应用和前景

二维（2D）MXene衍生的量子点（MQD）的开发尚处于早期阶段，但是由于其高电导率，丰富的活性催化位点，易于调整的结构，令人满意的分散性，出色的光学特性，引起了人们的极大兴趣性能，良好的生物相容性，多种功能化等等。但是，到目前为止，还没有关于MQD的评论文章。在此，MQD的研究进展包括其合成路线（自上而下和自下而上的方法），性质（结构，电子，光学和磁性性质），功能化（表面改性，杂原子掺杂和复合材料的构造）及其应用（传感，生物医学，催化，能量存储和光电设备等。），并重点讨论了MQD的未来前景和挑战。这篇综述将作为理解MQD最先进开发的一站式方法，并有望启发研究人员使用MQD来满足各种应用程序不断增长的需求。
