摘要: MXenes作为一种新兴的二维(2D)层状材料,具有电子导电率高、比表面积大、亲水性良好以及表面基团可控等优点,在能源、催化、防腐蚀和电磁屏蔽等领域展现出广阔的应用前景。其中,Mo2CTx MXene因优异的电催化析氢活性而备受关注。本文旨在系统梳理Mo2CTx MXene的制备及其在电催化析氢领域的研究现状,为该体系进一步深入研究提供全面且清晰的参考框架。文中全面综述了近年来Mo2CTx MXene的制备方法及分层技术;归纳了Mo2CTx MXene作为析氢反应(HER)电催化剂的研究进展;从末端修饰、元素掺杂以及杂化复合等角度深入探讨了Mo2CTx MXene HER催化性能的优化策略;最后对Mo2CTx MXene及其复合材料在电催化析氢领域的发展进行了展望。尽管Mo2CTx MXene的研究成果颇丰,但其制备工艺的绿色化与规模化不足,导致生产成本居高不下。此外,催化机理研究的滞后,制约了理性设计策略的开发。未来需着力开发绿色无氟制备工艺,促进材料规模化生产,持续提升催化活性并增强催化剂稳定性,加快催化机理的探究,以推动Mo2CTx及其复合材料在电催化析氢领域的应用进程。

Abstract: MXenes, an emerging family of two-dimensional (2D) materials with high electronic conductivity, large specific surface area, good hydrophilicity, and regulable surface functional groups, have shown broad application prospects across the domains of energy, catalysis, corrosion prevention, and electromagnetic shielding. Among numerous MXenes, Mo2CTx MXene has attracted much attention due to its excellent electrocatalytic hydrogen evolution activity. This paper aims to systematically review the preparation of Mo2CTx MXene and its current research status in the field of electrocatalytic hydrogen evolution, providing a comprehensive and clear reference framework for further in-depth study of this system. The synthesis methodologies and exfoliation techniques of Mo2CTx MXene in recent years are comprehensively reviewed; the research progress of Mo2CTx MXene as an electrocatalyst for hydrogen evolution reaction (HER) is summarized; the optimization strategies for the catalytic performance improvement of Mo2CTx MXene for HER are deeply explored from the perspectives of terminated group modification, elemental doping, and hybridization. Finally, a prospective outlook regarding Mo2CTx MXene-based composites in the realm of electrocatalytic hydrogen evolution is presented. Despite of significant research advancements on Mo2CTx MXene, the absence of eco-friendly and scalable preparation methodologies remains a critical challenge, contributing to elevated production costs. Additionally, the delayed progress in catalytic mechanism investigations hinders the formulation of rational design strategies. Henceforth, efforts should focus on developing green, fluorine-free synthesis approaches to facilitate large-scale material production, concurrently enhancing catalytic activity and catalyst stability, and accelerating the exploration of catalytic mechanisms. These endeavors are critical to advancing the practical application of Mo2CTx and its composite materials in the field of electrocatalytic hydrogen evolution.
