Hollow alpha-Fe2O3 nanospheres were synthesized by using novel carbon spheres as templates By carefully controlling the fundamental experimental parameters porous nanospheres with diameters of 60-80 nm and nanojujubes with diameters of 80-100 nm have been efficiently obtained respectively The growth mechanism and magnetic properties are also discussed in detail The coerovity values of the hollow alpha-Fe2O3 nanospheres and nanojujubes are much higher than those of other alpha-Fe2O3 nanomaterials Due to the unique morphology with cavum and porous wall the ferromagnetic nanospheres could be promising candidates as a magnetic carrier for drug targeting (C) 2010 Elsevier Masson SAS All rights reserved
