摘要
MXene因其优异的物理和化学特性,在电解水领域极具应用潜力。对电解水阴极析氢反应和阳极析氧反应中使用的MXene基材料进行了归纳和总结,通过分析可知,非金属元素掺杂、单/多金属元素负载以及结构设计等策略,已成为提高MXene电催化性能强有力的手段。此外,针对MXene在构建电解水催化剂中存在的缺点,诸如种类有限、表面基团不可控、易氧化、污染性等,提出了开发MXene新种类、寻找新型合成方法、与纳米材料复合增强稳定性以及采用无氟环保刻蚀剂等应对策略。
MXene possesses great potential for water electrolysis application due to its excellent physical and chemical properties.In this paper,MXene-based composites used in hydrogen evolution reaction and anode oxygen evolution reaction were summarized.Through the analysis,we can see that non-metal element doping,single/multi-metal element loading and the structure design have become powerful means to improve the performance of MXenes electrocatalysis.Aiming at the shortcomings of MXene in the construction of electrolytic water catalyst,such as limited species,uncontrollable surface groups,easy oxidation and pollution,we propose the corresponding coping strategies,i.e.developing new types of MXene,searching for new synthesis methods,compositing with nano-materials to enhance stability,and using fluorine-free environment-friendly etchants,to solve those problems.
