摘要: 采用氯化铁、氢氧化钠和少量水在乙二醇中进行常压加热反应得到了尺寸可控、形貌均匀的介晶结构四氧化三铁纳米粒子。所得纳米粒子饱和磁化强度为726 emu·g-1,既具有超顺磁性,又表现快速的磁响应特性。体系中少量水分的存在十分重要,没有水的参与反应不能进行。随着水加入量的增加,所得纳米粒子的尺寸逐渐变小。

Abstract: Fe3O4 mesocrytals with controllable size and uniform morphology were synthesized by the reaction of FeCl3, NaOH, and water in ethylene glycol at atmospheric pressure. The asprepared Fe3O4 mesocrystals exhibit superparamagnetic behavior with a high saturation magnetization of 72.6 emu·g-1 and possess a rapid magnetic response to external magnetic fields. Trace amounts of water in the reaction solution are necessary to trigger the formation of Fe3O4. The reaction cannot take place without water. As the amount of water added increased, the size of the nanoparticles obtained gradually decreased.
