“…By using bimetallic NPs, Kim reported on the performance of NiCu nanorods incorporated on carbon nanofibers (NiCu nanorods@C nanofibers) and highlighted the good stability of the catalyst, which retained its initial activity following six cycles 78 . A different system based on Fe-Ni NPs on polyethyleneimine (PEI)-decorated graphene oxide was reported by Lu (PEI-GO/Fe-Ni) 79 .…”

There is an evident urgent need to find a renewable and clean energy vector to ensure the worldwide energy supply while minimizing environmental impacts, and hydrogen stands out as a promising alternative energy carrier. The social concern around its safe storage is constantly fostering the search for alternative options to conventional storage methods and, in this context, chemical hydrogen storage materials have produced abundant investigations with particular attention to the design of heterogeneous catalysts that can boost the generation of molecular hydrogen. Among the chemical hydrogen storage materials, formic acid and ammonia-borane hold tremendous promise, and some of the recent strategies considered for the preparation of high-performance carbon-supported catalysts are summarized in this review. The outstanding features of carbon materials and their versatility combined with the tunability of the metal active phase properties (e.g., morphology, composition, and electronic features) provide numerous options for the design of promising catalysts.

“…Moreover, there is a significant and increasing interest in Ni-Cu alloys [7][8][9][10] which is related to their good corrosion resistance [11][12][13][14], mechanical [15][16][17], magnetic [18,19] and optical properties [20]. Because of the expressed dynamic activity of Ni-Cu systems, their role as efficient and chemically stable catalysts is of growing interest [21][22][23] as well. In addition, due to combination of good mechanical, thermal and electrical properties, Cu-Ni alloys are widely used for marine applications [24,25].…”

a b s t r a c tPhase diagram of the Cu-In-Ni ternary system was investigated using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) methods. Experimentally obtained results were compared with the results of thermodynamic calculation of phase equilibria based on calculation of phase diagram (CALPHAD) method and literature data. Phase transition temperatures of alloys with overall compositions along three selected vertical sections Cu-In 0.5 Ni 0.5 , Cu-In 0.8 Ni 0.2 and x(In) = 0.4 were measured by DTA. Liquidus temperatures were experimentally determined and compared with the results of thermodynamic calculation. Identification of coexisting phases in samples equilibrated at 400°C and 500°C was carried out using SEM-EDS and XRD methods. Obtained results were compared with the calculated isothermal sections of the Cu-In-Ni ternary system at corresponding temperatures. Calculated liquidus projection and invariant equilibria of the Cu-In-Ni ternary system were presented.

“…Description of the measurement apparatus are used in hydrogen generation by gas volumetric method can be found elsewhere [4,5]. Typically, the aqueous solution of AB (1mmol) was stirred with the required amount of the prepared catalysts (30 mg) at 30 o C. The system was exposed to an irradiated visible light emitted by a mercury lamp (2000W).…”

“…The most efficacy is the hydrolysis process by using the robust catalysts [3,4]. Recently, many catalytic materials such as precious metals, transition metals, bimetallic, and trimetallic nanoparticles (NPs) are used in AB dehydrogenation due to their good catalytic activity and large surface area-tovolume atomic ratio [5].…”
