With their rich surface chemistry, high electrical conductivity, variable bandgap, and thermal stability, 2D materials have been developed for effective electrochemical energy conversion systems over the past decade. Due to the diversity brought about by the use of transition metals and C/N pairings, the 2D material MXene has found excellent applications in many fields. Among the various applications, many breakthroughs have been made in electrocatalytic applications. Nevertheless, related studies on topics such as the factors affecting the material properties and safer and greener preparation methods have not been reported in detail. Therefore, in this paper, we review the relevant preparation methods of MXene and the safer, more environmentally friendly preparation techniques in detail, and summarize the progress of research on MXene-based materials as highly efficient electrocatalysts in the electrocatalytic field of hydrogen precipitation reaction, nitrogen reduction reaction, oxygen precipitation reaction, oxygen reduction reaction, and carbon dioxide reduction reaction. We also discuss the technology related to MXene materials for hydrogen storage. The main challenges and opportunities for MXene-based materials, which constitute a platform for next-generation electrocatalysis in basic research and practical applications, are highlighted. This paper aims to promote the further development of MXenes and related materials for electrocatalytic applications.
二维材料凭借其丰富的表面化学性质、高导电性、可变带隙和热稳定性，在过去十年中被开发用于高效电化学能量转换系统。由于过渡金属和C/N配对的使用带来的多样性，二维材料MXene在许多领域都有出色的应用。在各种应用中，电催化应用已取得许多突破。然而，关于影响材料性能的因素以及更安全、更绿色的制备方法等主题的相关研究尚未详细报道。因此，在本文中，我们详细综述了MXene的相关制备方法以及更安全、更环保的制备技术，并总结了基于MXene的材料作为高效电催化剂在析氢反应、氮还原反应、析氧反应、氧还原反应和二氧化碳还原反应的电催化领域的研究进展。我们还讨论了与MXene材料储氢相关的技术。突出了构成基础研究和实际应用中下一代电催化平台的基于MXene的材料的主要挑战和机遇。本文旨在促进MXene及相关材料在电催化应用方面的进一步发展。
