Preparation and Composition-Structure-Thermal Stability Relation of a NovelOpen-framework Vanadium Phosphate (H3NCH2CH2NH3)3(VO)4(PO4)2(HPO4)4

摘要: A novel open-framework vanadium(W) phosphate(H3NCH2CH2NH3)3(VO)4(PP4)2(HPO4)4 (short for V2P3-en) has been prepared. It issynthesized hydrothermally in the presence of ethylenediamine (en) at 170℃ for 5 days byself-assembly from structurally simple precursors V2O5, H3PO4 and H2O. The compound ischaracterized by means of Fourier transform-infrared spectroscopy (FT-IR),Thermogravimetry-differential thermal analysis (TG-DTA), X-ray powder diffraction analysis (XRD) andScanning electron microscopy (SEM). Furthermore, the composition-structure-thermal stabilityrelation of V2P3-en is explored in terms of crystal chemistry, and the potential approach to theenhancement of its thermal stability is proposed.
