Liquid Organic Hydrogen Carriers

The storage of hydrogen is a challenge, because in its elemental form cryogenic temperatures or high pressures are needed. One approach to circumvent these unfavorable conditions is the chemical storage in liquid organic hydrogen carrier (LOHC) materials.

In our research we aim at the understanding of the dehydrogenation mechanisms of the LOHC material perhydro-N-ethylcarbazole on the model catalyst Pt(111).
From the XPS data shown above we gained detailed insight to the reaction intermediates and reaction temperatures.
