Bi2Fe4O9 nanoparticles were prepared at low temperature via a facile, one-step hydrothermal synthesis process using iron(M) nitrate nonahydrate(Fe(NO3)(3)center dot 9H(2)O) and bismuth nitrate pentahydrate (Bi(NO3)(3)center dot 5H(2)O) as starting materials and sodium hydroxide (NaOH) as the precipitant and mineralizer. XRD results indicate that the as-prepared nanoparticles are pure Bi2Fe4O9. SEM images reveal that the as-prepared Bi2Fe4O9 nanoparticles have a sheet-like morphology. The Bi2Fe4O9 nanoparticles thus obtained are paramagnetic at room temperature as shown by magnetic measurements.
