▎ 摘　　要

Carbon nanocapsules (CNCs) encapsulating vanadium carbide (VC) nanocrystals with a NaCl structure were synthesized by a gas-evaporation method using arc-discharge heating. The CNCs were observed by high-resolution transmission electron microscopy. The VC nanocrystals within the nanospaces of CNCs were truncated by low-index facets and were coated with several graphene layers, forming graphene/VC interfaces. The atomic configuration and interlayer spacings at the interfaces were found.
