Abstract
Provided is a hydrogen storage system including a solution including ethylenediamine bisborane (EDAB) and ethylenediamine (ED), in which the hydrogen storage system is capable of performing a reversible dehydrogenation/hydrogenation reaction at a temperature of 20° C. to 200° C. in the presence of a heterogeneous metal catalyst including ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Jr), platinum (Pt), nickel (Ni), iron (Fe), cobalt (Co), or a combination thereof.
Claims6
A method for preparing a hydrogen storage system comprising a solution comprising ethylenediamine bisborane (EDAB) and ethylenediamine (ED), wherein the hydrogen storage system is capable of performing a dehydrogenation/hydrogenation reaction including:
- obtaining hydrogen by dehydrogenation reaction the solution at a temperature of 20° C. to 200° C. in the presence of a heterogeneous metal catalyst comprising ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), platinum (Pt), nickel (Ni), iron (Fe), cobalt (Co), or a combination thereof;
- and regenerating EDAB by regenerating reaction the product of the dehydrogenation reaction in the presence of a reducing agent and H2O, the method comprising:
- preparing the EDAB;
- preparing a solution by mixing the EDAB and the ED;
- and
- loading the heterogeneous metal catalyst into the solution.
