Abstract
Nowadays, photocatalytic mechanism of water purification using nanoparticles has gained wider acceptance. For this purpose, Crystal form of TiO2 and N- TiO2 was prepared from TiCl4, Urea, NH4OH by sol-gel method and simple solid phase reaction followed by calcinations at a temperature of 400 °C for 4h at each. The synthesized photocatalysts were characterized using XRD, FT-IR, SEM and Uv-Visible diffuse reflectance spectra. In the experiment, it was found that the absorption edge of N-TiO2, were well efficient shift to visible light as compared to TiO2. The PD efficiency of the catalysts for MB was increased from 24.52 to 46.0% and 57.05 to 96.02% under solar radiation as the amount of the catalyst increase from 0.15 to 0.45 gram for TiO2 and N-TiO2, respectively. In addition, the PD efficiency of the catalysts for removal of MB was increased from 35 to 52.04 and 57.00 to 97.00 under solar radiation as the calcination temperature of the catalyst increase from 300 to 500 at all. However, Additional increase in catalyst loading and calcination temperature was found to decrease the degradation efficiency.
Keywords- Degradation, nanoparticles, catalyst loading, calcination and methylene blue
