| Abstract: | The nitrogen (N) doped Ti4O7 photocatalyst was prepared from urea as a nitrogen source by a microwave method. The resulting photocatalyst was characterized by X-ray diffraction (XRD), Field Emission Scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), UV–visible diffuse reflectance spectroscopy (UV–Vis DRS) and UV–vis spectroscopy (UV–Vis). 0.1 M N doped Ti4O7 photocatalyst exhibited methylene blue decomposition efficiency of 100% which was prepared by microwave treatment for above 30 min. Rate constant was found to be 0.028910 min?1 in the first order kinetic. |
