| Outline of Final Research Achievements |
The basic study was performed on a new class of nanoporous materials, "porous materials with single-graphene walls". While the graphene-growth mechanism on a metal-oxide surface has been unknown over decades, this work elucidated the mechanism. The clarification of the mechanism enabled us to use a variety of template materials including aluminum oxides, magnesium oxides, and calcium oxides, and thus, we have successfully extended the structural diversity of the porous materials with single-graphene walls. Moreover, this project revealed unique advantages and properties of the porous materials with single-graphene walls. Thus, we found the superior performances of this new type of material over conventional carbon materials in a variety of applications including electric double-layer capacitors, Pt support for polymer-electrolyte fuel cells, new type of heat pump based on force-driven phase transition, and sulfur support for all-solid Li-ion batteries.
