Spherical carbon nanobeads (solid and hollow) of two sizes of around and 250 nm (small) were synthesized by pyrolysing camphor vapour at 1000Β°C in an argon atmosphere, using ferrocene, as catalyst, for the first time. The EEL spectrum suggests the carbon beads to be nongraphitic and these are covere
