Tungsten oxide (WO3) nanoparticles have been synthesized by a simple precipitation method and utilized as photocatalyst for degradation of methylene blue (MB) dye under LED-visible light irradiation. This photocatalyst was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy and UV-visible spectroscopy to determine phase, morphology, vibration mode, and optical property.
