Rechargeable Hydrogen Storage System Based on the Dehydrogenative Coupling of Ethylenediamine with Ethanol
Abstract
A novel and simple hydrogen storage system was developed, based
on the dehydrogenative coupling of inexpensive ethylenediamine with
ethanol to form diacetylethylenediamine. The system is rechargeable and
utilizes the same ruthenium pincer catalyst for both hydrogen loading
and unloading procedures. It is efficient and uses a low catalyst
loading. Repetitive reversal reactions without addition of new catalyst
result in excellent conversions in both the dehydrogenation and
hydrogenation procedures in three cycles.

In support of the hydrogen economy: An efficient and
simple homogeneous hydrogen carrier system was developed based on the
dehydrogenative coupling of ethylenediamine with ethanol to form
diacetylethylenediamine. The same ruthenium pincer catalyst is used for
both hydrogen loading and unloading reactions.
