ABSTRACT
 
Our group has studied electronic structures and ionic structures of various materials, including graphene, metal-graphene interfaces, ionic solids, and ionic liquids. Motivations of these works are related to energy storage and energy conversion devices. In this presentation, we would like to cover mainly four topics in such a view point. We first discuss hydrogenation of graphene in the perspective of hydrogen storage. As discussed in our recent publications, the hydrogenation and dehydrogenation of graphene can have some significance as hydrogen storage media, only when the migration channels of hydrogen adatoms are activated on the graphene planes. The competition between amine and ammonium on graphene surfaces can provide a decent hydrogen exchange mechanism that can lead to hydrogen migration and hydrogen spillover. We also have investigated the structures of halogen anions on graphene and in graphitic galleries. This topic will be presented in relation to the long-pending puzzle about mobile fluoride anions in the fluorinated graphitic materials. If time is allowable, we would like to include discussions about some issues related to solar cells: the iodide anions transport in ionic liquid and catalytic activity of graphene-noble metal interfaces.
