摘要：

Graphite crystals have been synthesized with high productivities at low temperatures from ethylene decomposition on cobalt ferrite nanoparticles. The crude material, that consists in iron-cobalt alloyed nanoparticles dispersed in the graphitic structure, presents ferromagnetic behavior. A simple HCl washing yeilds to pure graphitic flakes. The results show a remarkable support effect as MWNT are produced if cobalt ferrite particles are supported on alumina.
