Summary, etc. Nano sized inverse trirutiles of composition Cr<sub>2</sub>WO<sub>6</sub> and N-doped Cr<sub>2</sub>WO<sub>6 </sub>have been prepared by sol-gel and solid state methods respectively. Urea has been used as a source of nitrogen for N-doping. These trirutiles have been characterized by powder X-ray diffraction (PXRD), FT-IR, TGA, scanning electron microscopy (SEM), energy dispersive spectra (EDS), and UV-visible diffuse reflectance spectroscopy (UV-vis DRS). N-doped Cr<sub>2</sub>WO<sub>6 </sub>is crystallized in the tetragonal lattice with space group P4<sub>2</sub>/mnm (136). The bandgap energy of both parent and N-doped materials is deduced from their UV-visible DRS profiles. The photocatalytic degradation of methylene blue and methyl violet aqueous solutions have been investigated using these oxides. Compared to the parent material, nitrogen doped Cr<sub>2</sub>WO<sub>6</sub> exhibits ~ 30% and ~ 20 % increase in visible light-induced photo-degradation of the methylene blue (MB) and methyl violet (MV), respectively.
