The rapid advancement of triboelectric nanogenerators (TENGs) has introduced a transformative approach to energy harvesting and self-powered sensing in recent years. Nonetheless, the untapped potential of TENGs in practical scenarios necessitates multiple strategies like material selections and structure designs to enhance their output performance. Given the various superior properties, MXenes, a kind of novel 2D materials, have demonstrated great promise in enhancing TENG functionality. Here, this review comprehensively delineates the advantages of incorporating MXenes into TENGs, majoring in six pivotal aspects. First, an overview of TENGs is provided, stating their theoretical foundations, working modes, material considerations, and prevailing challenges. Additionally, the structural characteristics, fabrication methodologies, and family of MXenes, charting their developmental trajectory are highlighted. The selection of MXenes as various functional layers (negative and positive triboelectric layer, electrode layer) while designing TENGs is briefed. Furthermore, the distinctive advantages of MXene-based TENGs and their applications are emphasized. Last, the existing challenges are highlighted, and the future developing directions of MXene-based TENGs are forecasted.
近年来，摩擦纳米发电机（TENGs）的迅速发展为能量收集和自供电传感带来了一种变革性方法。尽管如此，TENGs在实际应用中尚未开发的潜力需要通过材料选择和结构设计等多种策略来提高其输出性能。鉴于MXenes这种新型二维材料具有各种优异性能，它们在增强TENG功能方面展现出了巨大潜力。在此，本综述全面阐述了将MXenes纳入TENGs的优势，主要集中在六个关键方面。首先，对TENGs进行了概述，阐述了其理论基础、工作模式、材料考量和主要挑战。此外，还重点介绍了MXenes的结构特征、制备方法及其家族，勾勒了它们的发展轨迹。简要介绍了在设计TENGs时将MXenes用作各种功能层（负摩擦电层和正摩擦电层、电极层）的情况。此外，强调了基于MXene的TENGs的独特优势及其应用。最后，突出了现有挑战，并预测了基于MXene的TENGs的未来发展方向。
