To assess the ability of TiO 2 in the destruction of phenol, the test conditions were selected first. The two lamps, first with UV radiation and another one with visible radiation was used and for each experiment, the desired concentration of phenol in water was prepared. Also the synthesized photocatalyst were used in powder form and to spread them in a solution the magnetic stirrer was used. The wavelength of lights measured by a spectrometer. For the synthesis of TiO 2 , first the structure of the photocatalyst was modified by three surfactants Pluronic P-123, Pluronic F-127 and CTAB. XRD test were taken from each of the three photocatalyst and it was found that all three catalysts are in anatase phase and have crystals of 10-15 nm. After testing the photocatalysts with UV light, it was found that TiO 2 synthesized by P-123 by 64.41 ± 3.93% phenol destruction under the test condition was the best choice. In the second part TiO 2 mesopore was synthesized. XRD, UV-Vis DRS and nitrogen absorption and desorption tests were taken from this photocatalyst. From XRD test it was found that the catalyst is synthesized in the anatase phase. Also from BET equation the surface area of mesopore catalyst M-TiO 2 was obtained 107.2851 ±4.7641 m 2 /g and from BJH method in nitrogen absorption and desorption it was found that the catalyst has an average pore diameter of 13.55 nm and has a uniform pore size. The catalyst was used in the experiment of phenol destruction by UV lightand it was found that the ability of the photocatalyst in destruction of phenol in water is 44.91 ± 6.32%. In the third part SBA-15 was used, in the first method, SBA-15 was synthetized and then TiO 2 were deposited in its structure and the photocatalyst was named TiO 2 /SBA-15. In the second method through synthesis of SBA-15, Ti source was added and the synthesized photocatalyst named Ti-SBA-15. Nitrogen adsorption and desorption test for Ti-SBA-15 showed that the photocatalyst has a surface area of 848.0621 ± 4.8314 m 2 /g that is far greater than M-TiO 2 and TiO 2 /SBA-15. After phenol destruction experiment it was found that the Ti-SBA-15 photocatalyst has a higher potential in the destruction of phenol in water to 85.32 ± 1.72%. Then Cu-Ti-SBA-15, Ni-Ti-SBA-15 and Fe-Ti-SBA-15 photocatalysts were synthesized and it was found that the use of three metals Cu, Ni and Fe reduces the ability of the Ti -SBA-15 photocatalyst in the destruction of phenol in water. Then the most appropriate conditions for amount of photocatalyst, initial concentration of phenol and effect of H 2 O 2 on phenol destruction for Ti-SBA-15 were investigated and it was found that the most proper amount of photocatalyst Ti-SBA-15 equivalent 1 g/L. It was also found an increase in concentration of phenol reduces the ability of the photocatalyst in phenol destruction. The quality of photocatalysts synthesized in the third part tested by XRD, UV-Vis DRS and absorption and desorption of nitrogen. In another part visible light was tested for phenol destruction in water by using photocatalyst that finally it was found that synthesized photocatalysts have limited activity in the visible region.
