Role of an Aluminum Atom on Graphene for Hydrogen Adsorption

The effects of an aluminum atom on the hydrogen adsorption onto graphene are investigated. An aluminum atom can be attached on a graphene sheet by a bond with both covalent and ionic properties. Then, the electric charge is transferred from the aluminum atom to the graphene. The activation energy fo...

Zusammenfassung:	The effects of an aluminum atom on the hydrogen adsorption onto graphene are investigated. An aluminum atom can be attached on a graphene sheet by a bond with both covalent and ionic properties. Then, the electric charge is transferred from the aluminum atom to the graphene. The activation energy for the hydrogen adsorption is significantly lowered by the addition of the aluminum atom for both atomic and molecular adsorptions. The hydrogen adsorption energy is also lowered significantly by the aluminum atom.
