| Outline of Final Research Achievements |
Fe-included carbon nanohorns (Fe-CNH) were synthesized by gas-injected arc-in-water method. To open small pores on Fe-CNHs, oxidation treatment was performed on Fe-CNH under the conditions in CO2-N2, air, and ozone-dissolved water. As a result, Fe became magnetite by the treatment using N2-CO2 and ozone water, and the magnetic susceptibility of Fe-CNH increased. Furthermore, the specific surface area increased by 2.5 times by the treatment using CO2-N2. Total organic carbon in water increased when ozone react with carbon, so that the combination of ozone and Fe-CNH may not be preferable to make pure water. The activity of Fe-CNH is very high as catalyst support when biodiesel is produced.
