“…The former reaction path produces H 2 for human use, while the latter produces NH 3 that can poison Nafion membranes and fuel cell catalysts, so the latter reaction must be avoided. So far, the catalytic decomposition of hydrous hydrazine has reached 100% catalytic selectivity [67][68][69][70][71]. The catalytic kinetic is still very slow, which enormously blocks the practical application of the system.…”

Hydrous hydrazine (N2H4∙H2O) is a candidate for a hydrogen carrier for storage and transportation due to low material cost, high hydrogen content of 8.0%, and liquid stability at room temperature. Pt and Pt nanoalloy catalysts have been welcomed by researchers for the dehydrogenation of hydrous hydrazine recently. Therefore, in this review, we give a summary of Pt nanoalloy catalysts for the dehydrogenation of hydrous hydrazine and briefly introduce the decomposition mechanism of hydrous hydrazine to prove the design principle of the catalyst. The chemical characteristics of hydrous hydrazine and the mechanism of dehydrogenation reaction are briefly introduced. The catalytic activity of hydrous hydrazine on different supports and the factors affecting the selectivity of hydrogen catalyzed by Ni-Pt are analyzed. It is expected to provide a new way for the development of high-activity catalysts for the dehydrogenation of hydrous hydrazine to produce hydrogen.

Development Trends on Nickel‐Based Electrocatalysts for Direct Hydrazine Fuel Cells

Low temperature hydrazine fuel cells have been advocated as potential energy carriers by virtue of their exceptional power densities and carbon free containing byproducts. However, the large‐scale application of these renewable energy systems has been extremely inhibited by the insufficient performance and high cost of the state‐of‐art platinum (Pt) catalysts. To pursue better activity, electrocatalysts must demonstrate low operating overpotentials and high tolerances to poisoning species, which are critical factors for increasing the energy conversion efficiency. Despite the tremendous progress of Pt‐based catalysts, controlling sluggish kinetics on microscopic surfaces is still a serious issue because the accumulation of reaction product slugs onto surface may impede the liquid fuel transport to catalytic sites, resulting in a low activity. Thus, the development of earth abundant electrocatalysts with an improved activity is unambiguously a principal requirement. In this review, recent trends in the rational design and synthesis of Ni‐based electrocatalysts with various compositions for hydrazine oxidation reaction (HzOR) are summarized. In particular, development of multicomponent compounds and employment of Ni‐based materials for HzOR are demonstrated to be effective approaches from tuning the electrochemical performance of Ni‐based catalyst materials. Moreover, some potential challenges and prospects are deliberated to further advance the improvement of Ni‐based materials for effective HzOR.

“…Several classical methods have been reported for the preparation of MOFs supported metal nanoparticles catalysts, such as impregnation [49,50], deposition-precipitation [51,52] and colloidal deposition [53]. Impregnation method is a simple strategy for the preparation of the supported nanocatalysts, however, it is difficult to obtain a uniform particle size distribution [50].…”
