“…Transition metal carbides (TMCs) are often used as a substitute for noble metal catalysts due to their low production cost, good electrical conductivity, and stability. For example, metal carbides such as WC 136 and Mo x C 137 have been proven to be good HER electrocatalysts. At higher temperatures, transition metal carbides are formed by introducing carbon atoms into the metal lattice, which have catalytic properties and electronic structures similar to noble metal Pt catalysts.…”

The catalytic de/hydrogenation process is important in the fields of petrochemical refining, fuel synthesis, drug synthesis, CO2 conversion, and hydrogen synthesis, where the construction of low‐cost and high‐efficiency de/hydrogenation catalysts attracting significant attentions. The molybdenum carbide (MoxC), as a non‐noble transition metal carbide catalyst, has been widely investigated for hydrogen activation. Herein, the research progress and achievements of molybdenum carbide for catalytic de/hydrogenation are reviewed. Additional attention was paid to the structure and crystal phase of molybdenum carbide, and various modification strategies related to the catalytic activity regulation are summarized. Finally, the application prospect of molybdenum carbide catalysts is also discussed. This review provides a framework reference for further understanding the design and utilization of molybdenum carbide catalysts for catalytic de/hydrogenation and the key research problems to be addressed.

“…Secondly, there is still a lack of in-depth research about the structure of molybdenum carbide, and the difficulty lies in identifying the active center of the material. There is a need to further identify the site and physicochemical properties of the catalytic active center by combining computational [107] and experimental methods [108]. For example, the relationship between energy band structure, density of electronic states, and catalytic activity can guide more effective modulation of the activity of the catalytic site [109].…”

Hydrogen is an ideal alternative energy for fossil fuels to solve aggravating environmental and energy problems. Electrocatalytic hydrogen evolution reaction (HER) driven by renewable electricity (sunlight, wind, tide, etc.) is considered to be one of the most promising approaches for hydrogen production. However, its large-scale applications are greatly limited by the use of noble platinum (Pt) group electrocatalysts. As an earth-abundant/non-noble HER catalyst, molybdenum carbide (MoxC: MoC or Mo2C) has attracted extensive attention in the field of sustainable hydrogen production due to its excellent Pt-like catalytic activity, low cost, high chemical stability, and natural abundance. In this review, the progress on the strategies for optimizing the catalytic activity of MoxC is summarized, including optimization of synthesis methods, composites with carbon material, non-precious metal doping, transition metal doping, construction of the heterogeneous structure, etc. Among them, the importance of sulphur-doping, Ni-doping, and heterophase structure on molybdenum carbide-based catalysts for enhancement of HER activity has been highlighted. In addition, molybdenum carbide-based bi-functional catalysts are presented for the application in full water splitting. Finally, several effective strategies for molybdenum carbide-based catalyst design are concluded, and challenges remained in electrocatalytic water splitting are raised. Future development trends and perspectives for this promising material are also discussed.
