Investigation of the Electrocatalytic reduction of simple ketones in alkaline media

Electrochemistry Communications
Electrochemical energy storage in organic compounds has gained increasing interest recently. In particular, ketones and their secondary alcohols can serve as an electrochemical liquid organic hydrogen carrier (EC-LOHC) due to the possibility of selective

Messung von Hydrierkinetiken flüssiger Wasserstoffträger (LOHC)

LOHC speichern Wasserstoff durch reversible Hydrierung aromatischer Verbindungen. In dieser Arbeit wurde ein Versuchsaufbau zur Analyse der Hydrierung mittels in-situ Raman-Spektroskopie entwickelt. Untersucht wurden Toluol als Modelkomponente für homocyclische LOHC und N-Ethylcarbazol als Vertreter der heterocyclischen LOHC.

Liquid Organic Hydrogen Carrier Concepts and Catalysts for Hydrogenation and Dehydrogenation Reactions

Molecules
Background: The issue of renewable energy (RE) source intermittency, such as wind and solar, along with the geographically uneven distribution of the global RE potential, makes it imperative to establish an energy transport medium to balance the energy ...

Model Catalytic Studies on the Thermal Dehydrogenation of the Benzaldehyde/Cyclohexylmethanol LOHC System on Pt(111)

Chemistry – A European Journal
AbstractWe investigated the dehydrogenation reaction and the thermal robustness of the liquid organic hydrogen carrier (LOHC) couple benzaldehyde/cyclohexylmethanol on a Pt(111) model catalyst in situ in synchrotron radiation photoelectron spectroscopy‐ and complementary temperature‐programmed desorption experiments.
