Nanocrystalline TiO2 and sulfur-doped TiO2 were synthesized using the sol-gel method. Tween-80,titanium tetraisopropoxide (TTIP), and sulfuric acid were employed as raw materials for the synthesisof TiO2. All the synthesized samples were heated for 3 h at 500 ºC. Each cell parameter of the preparedsamples was explored by employing the Rietveld refinement of X-ray diffraction (XRD) patterns. Forsulfur-doped TiO2 and TiO2 samples, considerable differences were observed in their cell parameters.Under ultraviolet (UV) irradiation, the phenol and remazol yellow (RY) photodegradation of the sinteredsamples was analyzed. Physical properties were studied using Brunauer-Emmett-Teller (BET) andtransmission electron microscopy (TEM) analyzes to measure the surface area. The XRD resultsconfirmed that except nano-anatase, no other phase was present in any sample. The particle size rangeis 10-15 nm. BET surface results showed that doping concentrations influenced the surface area. Onthe samples with a larger surface area, photodegradation is superior, which coincides with a higherdoping concentration.
