摘要

要解决与二氧化碳排放相关的紧迫挑战,就必须寻求经济、可持续的电催化剂来促进氢进化反应(HER)。碳化钼基纳米材料具有类似铂的催化能力、优异的稳定性及其晶相的多样性,因此已成为极具潜力的氢进化反应电催化剂。在这篇综述中,我们探讨了合成碳化钼的各种方法,包括固-气、固-固和固-液相反应。此外,我们还对通过水电解产生氢气的过程进行了深入阐释。此外,还介绍了一系列旨在提高碳化钼在氢转换环境中的性能的创新策略,包括相变工程、异质结构的构建、异质原子掺杂、混合结构与碳材料的整合、缺陷工程和细致的表面改性等尖端技术。综述最后强调了制氢电催化剂目前面临的挑战和广阔的发展前景,并重点介绍了基于碳化钼的催化剂。

Review—Recent Advancements in Molybdenum Carbides for Efficient Hydrogen Evolution Reaction
The quest for economical and sustainable electrocatalysts to facilitate the hydrogen evolution reaction (HER) is paramount in addressing the pressing challenges associated with carbon dioxide emissions. Molybdenum carbide-based nanomaterials have emerged as highly promising electrocatalysts for HER due to their Pt-like catalytic proficiency, exceptional stability, and the versatility of their crystal phases. Within this comprehensive review, we explore the diverse methodologies for synthesizing molybdenum carbides, including solid-gas, solid-solid, and solid-liquid phase reactions. In addition, a thorough elucidation of the hydrogen generation process through water electrolysis is provided. Furthermore, a spectrum of innovative strategies aimed at augmenting the performance of molybdenum carbides in the HER milieu is introduced, encompassing cutting-edge techniques such as phase-transition engineering, the construction of heterostructures, hetero-atom doping, the integration of hybrid structures with carbon materials, defect engineering, and meticulous surface modification. The review culminates by underscoring the current challenges and the promising prospects in the advancement of electrocatalysts for hydrogen production, with a dedicated focus on molybdenum carbide-based catalysts.
