Abstract

Abstract : We synthesized cobalt- (Co-) doped C60 nanowhiskers (NWs) by applying a liquid-liquid interfacial precipitation method using a C60 -saturated toluene solution and 2-propanol with Co nitrate hexahydrate (Co(NO3 )3 ⋅6H2 O). Heating the NWs at 873–1173 K produced carbon nanocapsules (CNCs) that encapsulated Co clusters with a hexagonal-closed-packed structure. After heating at 1273 K, the encapsulated Co clusters in CNCs were transformed into orthorhombic Co2 C clusters. It was found that Co- and Co2 C-encapsulated CNCs can be produced by varying heating temperature.
