Abstract
A nanocarbon aggregate including a graphite aggregate including a graphene sheet having a petal shape and a nanohorn. The petal-shaped graphite aggregate achieves a reduction in the particulate size and a higher dispersibility by allowing the edge of the petal shape to locally absorb a metal, a metal complex and a metal oxide. The nanocarbon aggregate is used for a catalyst support.

- 21. A nanocarbon aggregate comprising a graphite aggregate including one or a plurality of graphene sheets and having a petal shape as a whole.
- 31. A method for manufacturing a nanocarbon aggregate including a petal-shaped graphite aggregate and a nanohorn by using CO2 laser ablation, said method comprising controlling, in the CO2 laser ablation, a scanning rate of laser that scans a surface of a graphite target, intensity of the laser, and species and pressure of an ambient gas, to thereby control a content ratio of the petal-shaped graphite aggregate to the nanohorn.
- 32. A method for manufacturing a nanocarbon aggregate including a petal-shaped graphite aggregate and a nanohorn by using CO2 laser ablation, said method comprising performing an oxidation treatment on the nanocarbon aggregate obtained after the CO2 laser ablation, to thereby control a content ratio of the petal-shaped graphite aggregate to the nanohorn.
