Comprehensive Thermodynamic Study of Alkyl-Cyclohexanes as Liquid Organic Hydrogen Carriers Motifs

“…b Calculated as the sum of the S2. c Calculated by G3MP2 and atomization reaction, and corrected according to Equation (6). d Difference between columns 3 and 2 in this table.…”

“…In previous work, LOHC-systems composed of pairs of hydrogen-lean (aromatic) molecules and hydrogen-rich (aliphatic) molecules have been studied [5][6][7]. The thermodynamics of fully hydrogenated products have turned out to be very difficult to predict because of the high flexibility and complex conformational behavior.…”

Exploring the Dehydrogenation Reaction Pathway of Perhydro-Polycyclic Aromatic Hydrocarbons over the Pt/Al2O3 Catalyst as Liquid Organic Hydrogen Carriers by In Situ DRIFT

“…Low-carbon economy has been attracting more and more attention of the countries all over the world, − and it is necessary to develop a clean and renewable energy such as hydrogen to replace traditional fossil energy and reduce carbon emissions. − In the realization of hydrogen energy utilization, hydrogen storage and transportation are the tricky aspects at present. − Although high-pressure hydrogen storage as a feasible method for hydrogen storage has been widely used in the field of hydrogen fuel cell automobiles, it still has several problems such as low hydrogen storage density and the great safety hazards to be solved . In comparison, chemical hydrogen storage methods, which can achieve hydrogen storage by reversible hydrogenation and dehydrogenation of chemical materials, are more safe and have low cost. − Among all chemical hydrogen storage methods, liquid organic hydrogen carrier (LOHC) storage is considered to most likely realize large-scale application of hydrogen storage. − Polycyclic aromatic hydrocarbons (PAHs) such as toluene and dibenzyltoluene (DBT) have a high hydrogen storage rate and are suitable for use as LOHCs due to their unsaturated six-membered rings. , However, the dehydrogenation reaction of perhydro-PAHs takes place at least at 270 °C.…”
