Green synthesis of Fe3O4 nanoparticles embedded in a porous carbon matrix and its use as anode material in Li-ion batteries

A scalable and simple process was developed for the preparation of Fe3O4 nanoparticles embedded in carbon using nontoxic and affordable materials. The resulting composite showed a high reversible capacity of 702 mA h g(-1) as anode material in a Li-ion battery after 50 cycles.
