In this work, a tungsten oxide nanoparticle was developed with a simple method, using tungsten powder. The orthorhombic, hexagonal and monoclinic crystalline structures obtained were characterized by X-ray diffraction, scanning electron microscopy, as well as Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The coupling of these tungsten oxide nano particles with hydrogen peroxide is carried out on methyl orange removal from wastewater. The use of Hydrated orthorhombic particles showed the highest removal rate up to 89.7% comparatively to hexagonal and monoclinic crystalline structures respectively. The reusability of these particles showed a good stability with monoclinic crystalline structure after four cycles. Key words: Dyes, Tungsten Oxide, Catalysis, H2O2.we
