Morphology and structure of ammonium vanadates synthesis by hydrothermal method

Opis

The DataSet contains the XRD patterns, FTIR spectra, and scanning electron microscopy (SEM) micrographs of ammonium vanadates synthesis by hydrothermal method from different NH4VO3 precursors. The results reveal that a mixture of (NH4)V4O10xH2O and
(NH4)0.76V4O10 was obtained for both precursors, however the contribution of each phase was different for the samples that were obtained from different precursors. The morphology was also strongly affected by the type of precursor used.

The phase composition of obtained samples was examined by the X-ray diffraction method (XRD) by Philips X’Pert diffractometer system (Royston, UK) while using CuK radiation in the range of 5–80 degrees. The FT-IR spectra were recorded at room temperature while using a Perkin-Elmer spectrometer (model Frontier FTIR MIR/FIR) (Waltham, MA, USA). The FT-IR spectra of the samples that were pressed into KBr pellets with constant measure material concentration (0.5%) were collected in the wavenumber range 4000–400 cm^-1 (mid-IR region) while using the KBr beam splitter. The surface morphologies of the samples were studied by an FEI Company Quanta FEG 250 scanning electron microscope (SEM) (Waltham, MA, USA), mounting the analyzed sample on a carbon conductive tape.

These results are part of the project reported in Materials journal (10.3390/ma12203446) where the details about the synthesis are described.
