A facile method was developed for the synthesis of Fe₃O₄ nanoparticles with a higher specific surface area. Na₂CO₃ and hydrazine were added during the co-precipitation of ferrous and ferric species, without the assistance of any organic reagents or templates. The results show that the prepared Fe₃O₄ nanoparticles had a specific surface area of 286.9 m²/g, with satisfactory size and purity, thus exhibiting superparamagnetic properties with a relatively strong saturation magnetization (91 emu/g) at room temperature. This method is inexpensive, nontoxic, and reproducible.
