中文摘要：

以FeCl3·6H2O水溶液为前驱体,通过恒温水浴水解、表面活性剂组装和水热法强迫水解两种方法制备出了两种不同形态的β-FeOOH纳米棒自组装聚集体.采用XRD、FTIR和SEM等对产品的结构和形态进行了表征.实验表明：产品为结晶性良好的四方相结构,以一维的纳米棒自组装而成的有序聚集体.并讨论了表面活性剂的浓度和反应温度对纳米粒子组装的影响.

英文摘要：

β-FeOOH self-assembly nanorods with two different morphologies were prepared by constant temperature,surfactant assemble and forced hydrolysis from the precursor of FeCl3· 6H2O solution.The morphology and structure were characterized by XRD,FTIR,SEM.Experiment showed that the production was tetragonal,well crystalline,and self-assemble in order congeries with one-dimension nanorods.We also investigate the effect of concentration of surfactant and temperature on the assembly of nanoparticles.
