用三氯化铁和乙二胺四甲叉膦酸(edtmpH8)为原料合成膦酸铁(FeIII-edtmpH5)配合物前驱体, 再将该前驱体在空气氛下焙烧即制得偏磷酸铁Fe(PO3)3. 利用电喷雾质谱(ESI/MS)、红外光谱(FT-IR)、热重-差热分析(TG-DTA)测试确定了FeIII-edtmpH5配合物的组成和可能结构. 对焙烧后产物进行X射线衍射(XRD)、扫描电镜(SEM)及透射电镜(TEM)测试, 结果表明焙烧产物为具有三维网状形貌的高纯Fe(PO3)3.

The high pure Fe(PO3)3 with three-dimensional networks structure was synthesized by a novel thermal decomposition of phosphonate. Briefly, the iron phosphonate (FeIII-edtmpH5) complex was synthesized by using FeCl3 and ethylenediamine-tetramethylene phosphonic acid (edtmpH8) as starting materials. The composition and structure of FeIII-edtmpH5 complex is characterized by Fourier transform infrared spectroscopy (FT-IR), electrospray ionization/mass spectrometry (ESI/MS) and thermogravimetry-,differential thermal analysis (TG-DTA). Then, the Fe(PO3)3 is obtained by thermal decomposition of FeIII-edtmpH5 complex in air atmosphere. X-ray diffractometry (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) measurements show that the obtained Fe(PO3)3 possesses high purity, good crystallinity and particular three-dimensional networks morphology.
