“…Thus, the need for modification or further search for novel ones with the required robustness [37]. The application of heterojunctions such as nitrogen-doped Fe2O3/NiTe2 [38]; FeNi2S4/CoFe nanocomposite [39]; core-shell CoS2@N-doped carbon nanoneedle [40]; Pt/Porphyrin MOF nanoparticles [41] have been found to improve the robustness for hydrogen production.…”

“…Nevertheless, as already mentioned, they can be used as precursors for carbonaceous or metal oxide-based materials, after thermal treatment under different atmospheres (e.g., Ar, air, Ar/H 2 ), thus expanding their applicability. , The MOF-derived materials can show some properties inherited from the “parent” template MOF, and they are difficult to obtain with other methods. For example, MOFs and MTV-MOFs containing metalated porphyrins as building blocks can yield highly dispersed metallic NPs or even single atoms after a thermal treatment, thus taking advantage of the atomically dispersed distribution of metals in the parent porphyrinic structure. − However, the potential of metalated porphyrinic MOFs as catalyst precursors has not been fully realized yet, and their exploration has been mostly focused on carbon-based materials, almost neglecting the noncarbonaceous, metal oxide-based counterparts. , …”

The realization of the Hydrogen Economy involves the development of efficient, safe, and lightweight H storage and delivery systems. Hydrogen molecular carriers (HMCs) have been proposed for this application, as they release and store H 2 after catalyzed hydrogenation/dehydrogenation cycles, but efficient catalysts are still needed. In this work, we present a methodology for the development of nanocatalysts, using porphyrinic multivariate metal−organic frameworks (MTV-MOFs) as a precursor of supported nanoalloys/nanocomposites (M/ZrO 2 ). MTV-MOFs with PCN-222 structure, containing atomically distributed mixtures of Pd, Pt, and Ni, yield dispersed nanoalloys after calcination, with a high metal loading. Both support and catalytically active phases are produced simultaneously during thermal treatment. The obtained materials demonstrate synergistic effects in the catalytic dehydrogenation of hydrogen molecular carriers, namely, ammonia borane (AB), 2-methylpiperidine (2MP), and a liquid mixture of 2MP and DHC (dodecahydro-1H-carbazole).

“…To improve the efficiency of electrocatalysis for water decomposition, there is an immediate requirement to develop effective and reliable catalysts to expedite hydrogen evolution reaction (HER) dynamics [ 14 , 15 ]. Platinum is the most important HER catalyst owing to its suitable free energy of hydrogen adsorption [ 16 ]. However, as a noble metal catalyst, platinum is expensive and scarce, which limit its wide application [ 17 , 18 ].…”

In order to synthesize a high-efficiency catalytic electrode for hydrogen evolution reactions, nano-MoS2 was deposited in situ on the surface of graphite substrates via a one-step hydrothermal method. The effects of the reactant concentration on the microstructure and the electrocatalytic characteristics of the nano-MoS2 catalyst layers were investigated in detail. The study results showed that nano-MoS2 sheets with a thickness of about 10 nm were successfully deposited on the surface of the graphite substrates. The reactant concentration had an important effect on uniform distribution of the catalyst layers. A higher or lower reactant concentration was disadvantageous for the electrochemical performance of the nano-MoS2 catalyst layers. The prepared electrode had the best electrocatalytic activity when the thiourea concentration was 0.10 mol·L−1. The minimum hydrogen evolution reaction overpotential was 196 mV (j = 10 mV·cm−2) and the corresponding Tafel slope was calculated to be 54.1 mV·dec−1. Moreover, the prepared electrode had an excellent cycling stability, and the microstructure and the electrocatalytic properties of the electrode had almost no change after 2000 cycles. The results of the present study are helpful for developing low-cost and efficient electrode material for hydrogen evolution reactions.
