Transition-metal carbides and nitrides (MXenes) have attracted significant interest owing to their desirable properties, abundance, and high electrocatalytic activity. Tremendous studies have demonstrated the potential of MXenes for energy conversion and storage. However, further development of this potential must address various aspects of MXenes, including finite modification strategies, undefined reaction mechanisms, working life cycle, and additional untapped applications. In this Focus Review, we summarize the most recent progress in applications of MXenes and general guidelines for the rational design of MXene structures. The coupling of mixed-dimensional nanomaterials and the introduction of single atoms are discussed in the production of hydrogen, ammonia, and multi-carbon compounds, as well as energy storage applications. In addition, in situ characterization tools are briefly introduced as a potential means of shedding light on MXenes’ chemical activity. Finally, an outlook on future opportunities is provided to stimulate discussion and further research into MXene material synthesis and mechanisms.

基于 MXene 的异质结构在能量转换和存储方面的潜力

过渡金属碳化物和氮化物 (MXenes) 因其理想的性能、丰富性和高电催化活性而引起了人们的极大兴趣。大量研究证明了 MXenes 在能量转换和存储方面的潜力。然而，这种潜力的进一步发展必须解决 MXenes 的各个方面，包括有限修改策略、未定义的反应机制、工作生命周期和其他未开发的应用。在本次焦点回顾中，我们总结了 MXene 应用的最新进展以及合理设计 MXene 结构的一般指南。讨论了混合维纳米材料的耦合和单原子的引入在氢、氨和多碳化合物的生产以及储能应用中的应用。此外，简要介绍了原位表征工具，作为揭示 MXenes 化学活性的潜在手段。最后，提供了对未来机会的展望，以激发对 MXene 材料合成和机制的讨论和进一步研究。
