To realize sustainable development, more and more countries forwarded carbon neutrality goal. Accordingly, improving the utilization efficiency of traditional fossil fuel is an effective strategy for this great goal. Keeping this in mind, developing thermoelectric devices to recover waste heat energy resulted in the consumption process of fuel is demonstrated to be promising. High performance thermoelectric devices require advanced materials. MXenes are a kind of 2D materials with a layered structure, which demonstrate excellent thermoelectric performance owing to their unique physical, mechanical, and chemical properties. Also, substantial achievement has been gained during the past few years in synthesizing MXene based materials for thermoelectric devices. In this review, the mainstream synthetic routes of MXene from etching MAX were summarized. Significantly, the current state and challenges of research on improving the performance of MXene based thermoelectrics are explored, including pristine MXene and MXene based composites.
为实现可持续发展，越来越多的国家提出了碳中和目标。因此，提高传统化石燃料的利用效率是实现这一宏伟目标的有效策略。基于此，开发热电器件以回收燃料消耗过程中产生的废热能被证明是很有前景的。高性能热电器件需要先进的材料。MXenes是一种具有层状结构的二维材料，由于其独特的物理、机械和化学性质，表现出优异的热电性能。此外，在过去几年中，在合成用于热电器件的MXene基材料方面也取得了重大进展。在这篇综述中，总结了通过蚀刻MAX相制备MXene的主流合成路线。值得注意的是，还探讨了提高MXene基热电材料性能的研究现状和挑战，包括原始MXene和MXene基复合材料。
