PREPARATION, CHARACTERIZATION AND PHOTOCATALYTIC STUDIES OF Cr2(MoO4)3 AND NITROGEN-DOPED Cr2(MoO4)3

Cr2(MoO4)3 and N-doped Cr2(MoO4)3 are prepared by sol-gel and solid state methods, respectively. These molybdates are characterized by powder X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, thermogravimetric analysis, FT-IR and UV-visible diffuse reflectance spectroscopy. The photodegradation of methylene blue solution was investigated in the presence of these oxides.
