A variety of nanocarbons of different shapes and compositions (C, C-N) has been formed using a modified high isostatic pressure (HIP) apparatus. It was found that the presence of nitrogen in the background gas increases evaporation of graphite in the hot zone of the heater and increases the yield of carbon nanostructures. Carbon deposits formed by different gas pressures and temperatures were characterised using transmission electron microscopy and electron energy loss analytical microscopy.
