| Outline of Final Research Achievements |
Metal-free photocatalytic hydrogen evolution occurred efficiently in benzene containing single-walled carbon nanotubes under laser irradiation at 532 nm with an extremely high turnover number of 2 000 000 and a high quantum yield of 130%.
Laser pulse irradiation of a deaerated aqueous solution containing the solid state lithium ion-encapsulated fullerene resulted in the formation of highly dispersed nano-aggregates (Li+@C60)n. Photoirradiation of an O2-saturated D2O solution containing (Li+@C60)n gave singlet oxygen with 55% quantum yield, leading to efficient double-stranded DNA cleavage.
In conclusion, highly dispersed nanocarbons have new catalytic properties for hydrogen evolution and singlet oxygen generation.
