“…Similarly, 1 H-NMR spectra of diphenylmethane, 2-phenyltoluene, 3-phenyltoluene, and toluene ( Figure S3- Figure S10, Supporting Information) confirmed that the hydrogenation reactions of these materials were readily proceeded. [23,24] In agreement with our results, few previous literatures have reported that hydrogenation of naphthalene was achieved with different catalyst materials, such as Ni-W sulfide; [25] however, much higher reaction temperature ( � 380°C) was required to achieve a conversion rate of over 80 %. In Figure S12, Supporting Information, 1 H-NMR spectrum obtained for the reaction products of 1methylnaphthalene still exhibited the peaks located between 7 and 8 ppm corresponding to the aromatic protons, indicating that the hydrogenation reaction rate of 1-methylnaphthalene was significantly slower than those of other aromatic compounds, or that the reaction did not occur under the tested reaction conditions.…”

“…The observed inactivity of the 1-methylnaphthalene is likely attributed to its higher resonance energy (255.2 kJ mol À 1 ) compared to that (150.6 kJ mol À 1 ) of benzene. [23,24] In agreement with our results, few previous literatures have reported that hydrogenation of naphthalene was achieved with different catalyst materials, such as Ni-W sulfide; [25] however, much higher reaction temperature ( � 380°C) was required to achieve a conversion rate of over 80 %. These results suggested that naphthalene-based materials may not be good candidates for an efficient hydrogen storage system.…”

A novel, liquid‐phase hydrogen storage material was produced by mixing biphenyl (C12H10, solid) and diphenylmethane (C13H12, liquid) with a mass ratio (wt %) of 35:65. The eutectic mixture was proved to be liquid at ambient temperature with a viscosity of 3.0 cP at 25 °C and a vapor pressure of 1.4 Pa at 25 °C, which potentially meets the requirements for an efficient hydrogen storage system. A theoretical study using COSMO‐RS method further confirms that an optimum composition of biphenyl and diphenylmethane for the formation of eutectic mixture is 37:63 by mass, which is very close to the composition found experimentally. The eutectic mixture exhibited a superior activity for hydrogenation reactions conducted at 120 °C under 50 bar of H2 pressure in the presence of a Ru (5 wt %)/Al2O3 catalyst. Hydrogen uptake of the eutectic mixture tested was close to full conversion, which corresponds to 6.9 wt % and 60.1 g L−1 of gravimetric and volumetric hydrogen storage capacities, respectively.

Sulfide Catalysts Supported on Porous Aromatic Frameworks for Naphthalene Hydroprocessing

This paper describes the first example of using porous aromatic frameworks as supports for sulfide catalysts for the hydrogenation of aromatic hydrocarbons. The synthesis of bimetallic Ni-W and Ni-Mo sulfides was performed by in situ decomposition of [(n-Bu) complexes, supported on mesoporous aromatic framework with a diamond-like structure. It is shown that the highest naphthalene conversions were achieved in the case of additional sulfidation with sulfur. After the reaction, catalysts were characterized by X-ray photoelectron spectroscopy and high-resolution transmission electron microscopy. The activity of synthesized catalysts has been studied using naphthalene as a model substrate. The materials used in this study were substantially active in hydrogenation and slightly in hydrocracking of naphthalene.
