Outline of Final Research Achievements

The aim of this study is to elucicate the cooperative effect of graphene-based nanospaces and edge carbons on surface activity. We prepared the nanoporous graphene monolith of the high surface area of 2000 m2/g from edge carbon-rich nanographenes, which shows high water adsorption activity. The nanphthalene-derivative(ND)s as the model of edge carbon-rich molecules were doped in the interstitial spaces of single wall carbon nanotube bundles; the ND-doping increases the electrical conductivity by 50 times and enhances CO2 adsorptivity.
We prepared atomically 1D sulfur chain crystal of metallicity inside carbon nanotube below 0.1 MPa, while the metallica sulfur must be prepared under the compression with more than 90 GPa in the bulk phase. It was found that nanoporous carbon having small mesopores accelerated the formation of methane hydrate by more than 10 times.
