摘要
Bi_2Fe_4O_9 nanoparticles were prepared at low temperature via a facile, one-step hydrothermal synthesis process using iron(Ⅱ) nitrate nonahydrate(Fe(NO_3)_3·9H_2O) and bismuth nitrate pentahydrate (Bi(NO_3)_3·5H_2O) as starting materials and sodium hydroxide (NaOH) as the precipitant and mineralizer. XRD results indicate that the as-prepared nanoparticles are pure Bi_2Fe_4O_9. SEM images reveal that the as-prepared Bi_2Fe_4O_9 nanoparticles have a sheet-like morphology. The Bi_2Fe_4O_9 nanoparticles thus obtained are paramagnetic at room temperature as shown by magnetic measurements.
