Facet-dependent catalytic activities of Pd/rGO: Exploring dehydrogenation mechanism of dodecahydro-N-ethylcarbazole

Catalytic Consequences of Supported Pd Catalysts on Dehydrogenative H2 Evolution from 2-[(n-Methylcyclohexyl)methyl]piperidine as the Liquid Organic Hydrogen Carrier

“…Recently, various LOHC compounds were selected from the petroleum derivatives or rationally designed in the lab. − Carbon-based homocyclic molecules, such as benzyl toluene and dibenzyl toluene, and N-containing heterocyclic molecules, such as n -ethylcarbazole, have been considered as potential LOHC compounds. − Homocyclic LOHC compounds are more stable but less reactive than heterocyclic LOHC compounds. Most recently, 2-( n -methylbenzyl)­pyridine (H 0 -MBP), a bicyclic molecule consisting of two aromatic groups (benzene and pyridine), has been designed and synthesized in the laboratory .…”

Recent Advances of Catalysis in the Hydrogenation and Dehydrogenation of N-Heterocycles for Hydrogen Storage

“…Recently, Wang et al 51 investigated the effect of the metal surface on the catalytic process via calculating the adsorption energy of reactant 12H-NEC, intermediates 8H-NEC and on the Pd ( 100), (110), and (111) surfaces, with the Pd (100) surface having the most favorable energy.…”

“…Recently, Wang et al investigated the effect of the metal surface on the catalytic process via calculating the adsorption energy of reactant 12H-NEC, intermediates 8H-NEC and 4H-NEC, and the final product NEC on Pd (100), (110), and (111). As shown in Figure , 12H-NEC, 8H-NEC, and 4H-NEC are prone to adsorb on the hollow sites of Pd surfaces, where the six-membered ring is parallel to the three Pd surfaces.…”

“…Top and side views of the optimized adsorption configurations of (a) 12H-NEC, (b) 8H-NEC, (c) 4H-NEC, and (d) NEC on Pd (111), (110), and (100) surfaces. Reprinted with permission from ref . Copyright 2020 Elsevier.…”

Benzyltoluene/perhydro benzyltoluene – pushing the performance limits of pure hydrocarbon liquid organic hydrogen carrier (LOHC) systems

“…7 This is also the reason why, in recent years, the development of pure hydrocarbon LOHC systems has outpaced interest in N-containing LOHCs, although the latter have lower heats of dehydrogenation enabling slightly lower dehydrogenation temperatures. 8,9 Their disadvantage of not being fully compatible with the existing fuel infrastructure makes their introduction and use much more complicated and less attractive. 10…”
