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.
