自 2011 年首次发现 MXenes 以来，已经基于不同过渡金属的组合开发了各种 MXenes 成分。它们卓越的和耐人寻味的特性，例如出色的电子导电性、亲水性和易于大规模合成，使它们成为各种应用的候选者，包括能量存储、EMI 屏蔽、生物医学、透明导电薄膜、电催化等。然而，大多数努力都集中在碳化物 MXenes 上，而非碳化物（碳氮化物和氮化物）MXenes。使用非碳化物 MXene 中的负电氮，会在导电网络中感应出额外的负电荷，从而增强其润湿性、导电性和赝电容等特性。它们的合成困难一直是非碳化物MXenes研究进展的重要权宜之计。在这篇综述中，我们全面概述了非碳化物 MXenes 的合成、性质和应用，强调了碳化物和非碳化物 MXenes 之间的区别，以便更好地理解。简要讨论了非碳化物 MXene 的挑战和局限性以及规避它们的方法。

2D non-carbide MXenes: an emerging material class for energy storage and conversion

Since the first discovery of MXenes in 2011, various compositions of MXenes have been developed based on the combinations of different transition metals. Their exceptional and intriguing properties, such as excellent electronic conductivity, hydrophilic nature, and ease of large-scale synthesis, enabled them to be candidates for diverse applications, including energy storage, EMI shielding, biomedical, transparent conductive films, electrocatalysis, etc. However, most efforts have been focused on carbide MXenes and not much on non-carbide (carbonitride and nitride) MXenes. With electronegative nitrogen in non-carbide MXenes, an additional negative charge is induced in the conductive network, enhancing their properties such as wettability, conductivity, and pseudocapacitance. The difficulty in their synthesis has been a significant stopgap in the research progress of non-carbide MXenes. In this review, we have provided a comprehensive overview of the synthesis, properties, and applications of non-carbide MXenes, emphasizing the difference between carbide and non-carbide MXenes for better understanding. The challenges and limitations of non-carbide MXenes and the ways to circumvent them are briefly discussed. The future research directions and the opportunities are also discussed to encourage researchers to investigate non-carbide MXenes further.
