采用乙二醇法自组装工艺，用廉价无毒的三氯化铁合成了3D花状氧化铁纳米结构(见图)。在氧化铁前驱体的形态演变过程中，确定了一个两阶段的生长过程。具有相同花状结构的α-Fe_2O_3、γ-Fe_2O_3和Fe_3O_4很容易从相同的前驱体中获得，但经过不同的焙烧程序。所得到的氧化铁对水中各种污染物具有很好的去除能力。
An ethylene-glycol-mediated self-assembly process is adopted to synthesize 3D flowerlike nanostructures of iron oxide (see figure) using inexpensive and nontoxic ferric chloride. A two-stage growth process is identified during the morphological evolution of the iron oxide precursor. alpha-Fe2O3, gamma-Fe2O3, and Fe3O4 with the same flowerlike structure are readily obtained from the same precursor but by different calcination procedures. The as-obtained iron oxides show excellent ability to remove various pollutants from water.
