Ni–Cu High-Loaded Sol–Gel Catalysts for Dehydrogenation of Liquid Organic Hydrides: Insights into Structural Features and Relationship with Catalytic Activity

“…In general, the high cost of noble metals, and sometimes their insufficient selectivity in the target dehydrogenation reaction, prompts reduction of the use of precious metal catalysts by the introduction of a second metal (Ni, Sn, Mn, etc. [9,[17][18][19][20][21]) and the search for alternative catalytic systems. In particular, non-precious monometallic catalysts based on Ni, Mo, Cu, Ag, Zn, and Sn have been proposed [22][23][24][25].…”

Microwave-Mediated Site-Selective Heating of Spherical-Carbon-Bead-Supported Platinum for the Continuous, Efficient Catalytic Dehydrogenative Aromatization of Saturated Cyclic Hydrocarbons

“…It is imperative to expand the use of clean energy sources to mitigate the impending global climate crisis, which is a result of our dependence on fossil fuels. The combustion of hydrogen, which does not release greenhouse gases, has been proposed as an environmentally friendly method of energy production. − Hydrogen is produced industrially by the steam reforming of feedstocks such as methane and methanol, which are themselves produced from fossil fuels under harsh conditions, along with the production of carbon dioxide. − Fuel cells are an attractive technology for use as a hydrogen energy vector . Because the energy density per unit volume of hydrogen is rather low (11.9 MJ m –3 for hydrogen versus 34.6 MJ m –3 for gasoline) unlike its high energy density per weight (242 MJ kg –1 for hydrogen versus 49 MJ kg –1 for gasoline), it is necessary to liquefy hydrogen for storage, which is an energy-intensive process.…”

“…The liquid organic hydride method of hydrogen storage has several advantages; for example, the liquid can be handled at ambient temperature and pressure and can be reused via the hydrogenation–dehydrogenation cycle. Cyclohexane, , methylcyclohexane (MCH), − and decalin ,,, are regarded as good candidates for the liquid organic hydride technique. In particular, MCH is the best candidate liquid organic hydride because both MCH and toluene exist as liquids over a wide temperature range (−94 °C to 101 °C).…”

“…The catalytic dehydrogenation of MCH is a crucial technique. Many heterogeneous transition metal (e.g., Pt, Pd, and Ni) catalysts supported on various materials, such as carbon, alumina, and silica gel, have been developed for use as dehydrogenation catalysts for MCH. − However, the dehydrogenation reaction requires a great deal of energy and, thus, high temperatures (>270 °C) and pressures because of the endothermic nature of the MCH dehydrogenation reaction. Consequently, the deterioration of the catalyst over the course of the reaction is virtually inevitable.…”

“…The catalytic dehydrogenation of hydrocarbons to construct aromatic skeletons that are useful building blocks for various functional materials − has also drawn attention as an oxidant-free and less wasteful oxidative method. ,, The reported catalytic dehydrogenative aromatization of alicyclic compounds usually requires at least one or more unsaturated bonds within the cyclic structure. , Although heterogeneous catalytic dehydrogenative aromatization of fully saturated alicyclic hydrocarbons has been reported in the literature, − ,, such reactions are limited to the substrate scope − , and represent a comparatively low reaction efficiency. , Therefore, the development of an effective aromatization method for fully saturated alicyclic compounds including heterocycles is challenging.…”
