Abstract:

(Y2O3) and ethyl acetate as a mineralizer by hydrothermal method at a low temperature (T=.230°C, and

P=100bars).The as-prepared powders were characterized by X-ray Diffraction (XRD), Fourier Transform Infrared

Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), UV-V Spectroscopy and Chemical Oxygen Demand

(COD) of the sewage water, respectively. The results show that hydrothermal method can greatly promote the

crystallization and growth of YVO4 phase. XRD pattern clearly indicates the tetragonal structure and crystallanity. An

FTIR spectrum of the YVO4 shows the presence of Y-O and V-O bond, respectively. The presence of these two peaks

indicates that yttrum vanadate has been formed. UV-V is absorption spectra suggesting that YVO4 particles have

stronger UV absorption than natural sunlight and subsequent photocatalytic degradation data also confirmed their

higher photocatalytic activity.

In this paper, YVO4 powder was successfully synthesized from Vanadium Pentaoxide (V2O5), Yttrium Oxide
