“…Indeed, when Pt is used, an ultrapure H 2 feed (>99.99%) is required to avoid its deactivation [115]. Many catalytic-supported systems have been proposed [116]. Alumina (Al 2 O 3 ) is usually the supporting phase, functionalized with a transition metal such as Ni, Co, or Mo.…”

“…Nevertheless, these catalysts provide lower activity than Pt towards hydrogenation, requiring more severe operating conditions. Zhou et al [116] proposed an Fe-promoted Mo carbide catalyst; they investigated the effect of iron load (Fe:Mo ratio) and carburization temperature (550-700 • C) on catalytic activity and stability. The addition of iron slightly affects the hydrogenation activity, while strongly improving the stability over time.…”

Hydrogen carriers are one of the keys to the success of using hydrogen as an energy vector. Indeed, sustainable hydrogen production exploits the excess of renewable energy sources, after which temporary storage is required. The conventional approaches to hydrogen storage and transport are compressed hydrogen (CH2) and liquefied hydrogen (LH2), which require severe operating conditions related to pressure (300–700 bar) and temperature (T < −252 °C), respectively. To overcome these issues, which have hindered market penetration, several alternatives have been proposed in the last few decades. In this review, the most promising hydrogen carriers (ammonia, methanol, liquid organic hydrogen carriers, and metal hydrides) have been considered, and the main stages of their supply chain (production, storage, transportation, H2 release, and their recyclability) have been described and critically analyzed, focusing on the latest results available in the literature, the highlighting of which is our current concern. The last section reviews recent techno-economic analyses to drive the selection of hydrogen carrier systems and the main constraints that must be considered. The analyzed results show how the selection of H2 carriers is a multiparametric function, and it depends on technological factors as well as international policies and regulations.

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.
