Crystal form of N-TiO2/WO3 Nano-Composite material was prepared from urea, commercial TiO2 and WO3 by simple solid phase reaction followed by calcination at a temperature of 400 0C for four hours at each step. The as-synthesized photocatalyst was characterized using XRD and Uv-Visible diffuse reflectance spectra. It was found that the absorption edge of N-TiO2/WO3 was well extended to visible light. The effect of catalyst loading and initial pH on the photocatalytic efficiency of the sample was tested using phenol red as a target pollutant. The photocatalytic degradation efficiency of the catalyst for the adsorbed phenol red was increased from 61.75-93.87% under visible and 48.01-75.74% under UV as the amount of the catalyst increase from 0.15 to 0.45 gram. Further increase in concentration was found to decrease the degradation efficiency. The photocatalytic degradation efficiency of adsorbed phenol red was increased from 55.88-95.23%, under visible and 44.18 -77.32%, under UV as the pH of the solution decreased from 5 to 3. But further decrease in pH was found to decrease the degradation efficiency. The assynthesized photocatalyst was highly efficient under visible irradiation than under UV irradiations.
