Dehydrogenation of polycyclic naphthenes on a Pt/C catalyst for hydrogen storage in liquid organic hydrogen carriers

Study of catalytic hydrogenation and dehydrogenation of 2,3-dimethylindole for hydrogen storage application

“…However, with high enthalpy of dehydrogenation (>60 kJ mol À1 H2), the operation temperatures of these hydrogenated cycloalkanes were required over 300 C, which typically lead to the molecule cracking or coking. [27][28][29] Hence, a large number of literatures concerning the catalysts development for dehydrogenation of cycloalkanes were reported in decades. [30][31][32][33][34][35][36][37] In 2004, a series of heteroaromatic molecules with relatively low heat of hydrogenation screening as LOHCs were rstly studied through systematic experimental and theoretical by Pez et al 38,39 It is reported that incorporation of N heteroatom into the aromatic ring favored the dehydrogenation thermodynamics and kinetics.…”

Chemical modification in and on single phase [NiO]0.5[Al2O3]0.5 nanopowders produces “chocolate chip‐like” Nix@[NiO]0.5‐x[Al2O3]0.5 nanocomposite nanopowders

“…[23][24][25][26] Theoretically, transition metal aluminum spinel oxides, especially nickelcontaining, offer considerable potential and practical applications as catalysts for such reactions as hydrocarbon cracking, methane-and methanol-steam reforming, and dehydrogenation. [27][28][29][30][31][32] Alumina supported nickel catalysts are relatively inexpensive compared to other types of catalysts. Therefore, considerable effort has been devoted to exploring and optimizing their properties.…”

“…Spinel oxide crystal lattice ions often form with both 2 + and 3 + ions found interchangeably in both the tetrahedral and octahedral positions depending on the elements involved and leading to a wide variety of properties . Theoretically, transition metal aluminum spinel oxides, especially nickel‐containing, offer considerable potential and practical applications as catalysts for such reactions as hydrocarbon cracking, methane‐ and methanol‐steam reforming, and dehydrogenation . Alumina supported nickel catalysts are relatively inexpensive compared to other types of catalysts.…”

Insight into the adsorption of a liquid organic hydrogen carrier, perhydro-i-dibenzyltoluene (i = m, o, p), on Pt, Pd and PtPd planar surfaces

“…[19][20][21][22] Toxicity: some of the elemental materials used, or by-products, are toxic. 16,[23][24][25] Because of these challenges, there is great need for a sustainable energy solution that will not suffer from the shortcomings mentioned (cost, storage, transportation, integration and toxicity). Hydrogen and its associated technologies is one such solution.…”
