Abstract
- The degradation of organic dyes in the presence of modified TiO2 is still under intensive investigation. We report here an evaluation of the photocatalytic activity of nitrogen- (N-) and sulfur- (S-) doped TiO2 for the degradation of phenol and methylene blue (MB). N-doped TiO2 (N-TiO2), S-doped TiO2 (S-TiO2), and N-S-doped TiO2 (N-S-TiO2) were prepared using the sol-gel method. The photocatalytic activity was evaluated in a batch reactor using phenol and MB as models of pollutants. In addition, this investigation was performed using a household lamp as the visible light source. Properties of the synthesized materials in terms of Brunauer-Emmett-Teller (BET) surface analysis, field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), and photocatalytic ability were examined. Our study shows that N-S-TiO2 exhibits better photocatalytic degradation ability for all the considered dyes compared to the other doped TiO2 materials. In conclusion, we have successfully prepared and evaluated the photocatalytic activity of N- and S-doped TiO2 for the degradation of phenol and MB using an ordinary household lamp.
