Empty cages : Iron/graphite core–shell nanoparticles are produced by pyrolysis of a mixture of acetylene and iron carbonyl. Then, the core–shell nanoparticles are heat treated in the range of 300–500 °C in the presence of NH 4 Cl. After filtration in water, the trapped iron particles are completely removed and hollow carbon nanocages with a good graphitic structure are obtained (see graphic).
