Each bubble is about 3–10 nm in size and has a layered structure with typically one to four graphene layers. The CNF forms nanoparticles of about 100 nm in size. CNF encapsulating platinum nanoparticles (Pt@CNF) is formed when a mixture of graphite, platinum, and hexadecanoic acid is used as a target. Each bubble encapsulating a platinum nanoparticle is approximately 15±4 nm in diameter and contains typically 6±3 graphene walls. The platinum nanoparticles in the CNF are 9±4 nm in diameter. The annealing of the Pt@CNF at 300 °C for a week in vacuum reveals that the CNF effectively prevents the platinum nanoparticles from aggregating.
