本文介绍了聚丙烯酰胺凝胶法制备bi2fe4o9纳米粒子的方法。结果表明，使用不同的螯合剂可以制备出高相纯度的bi2fe4o9纳米颗粒。然而，有趣的是，发现产品的粒度取决于螯合剂的选择。利用EDTA作为螯合剂，可以制备出粒径相对较小的bi2fe4o9纳米粉体。光催化实验表明，制备的bi2fe4o9纳米颗粒在紫外光和可见光照射下对甲基红的氧化分解具有良好的光催化活性。磁滞回线测量表明，纳米bi2fe4o9在室温下表现出弱铁磁性。
In this report, a polyacrylamide gel route is introduced to synthesize Bi2Fe4O9nanoparticles. It is demonstrated that high-phase-purity Bi2Fe4O9nanoparticles can be prepared using different chelating agents. Interestingly, however, the particle size of the products is found to be dependent on the choice of chelating agent. The use of EDTA as the chelating agent allows the production of Bi2Fe4O9nanopowder with a relatively smaller particle size. The photocatalytic experiments reveal that the as-prepared Bi2Fe4O9nanoparticles possess excellent photocatalytic activity for oxidative decomposition of methyl red under ultraviolet and visible light irradiation. Magnetic hysteresis loop measurement shows that the Bi2Fe4O9nanoparticles exhibit a weak ferromagnetic behavior at room temperature.
