A simple technique for the synthesis of filled carbon nanoparticles

A new method has been developed for the production of filled carbon nanoparticles, which has many advantages over the usual arc-evaporation technique. The method involves high-temperature heat treatment of a microporous carbon which has been impregnated with a compound of the material to be encapsulated. In this study, this technique is used to synthesise nanoparticles filled with molybdenum, uranium and cobalt.
