Cobalt tungstate (CoWO4) nanoparticles were prepared by simple and cost effective precipitation method. The (CoWO4) nanoparticles were synthesized by reacting 1:1 mole ratio of Cobalt chloride and sodium tungstate. The synthesized nanoparticles were characterized by XRD, Raman, SEM and DRS-UV spectroscopy. The XRD pattern reveals that the synthesized (CoWO4) has monoclinic structure. In addition, by using the XRD data lattice parameter values also calculated. The Raman analysis confirms the presence of Co-O and W-O bonds in (CoWO4) nanoparticles. SEM analysis revels that the synthesized (CoWO4) are in nm rang. The optical property of (CoWO4) nanoparticles was carried out by DRS UV-Visible spectroscopy. The photocatalytic property of synthesis CoWO4 was investigated by degradation of methylene blue as the model pollutant.
