Both materials showed visible-light absorption as measured by Diffuse Reflectance Spectroscopy (DRS). Interstitial N-doping, anionic and cationic S-doping was found when the TiO2 was doped with thiourea while TiO2 doped with urea showed only the presence of interstitial N-doping as measured by X-ray Photo-electron Spectroscopy (XPS). The N content on the surface of N-doped TKP 102 photocatalyst was 2.85 at.%. and higher than the N content in the N, S co-doped TiO2 photocatalyst (0.6 at.%).Heterogeneous photocatalysisHelio-photocatalysisNitrogen doped TiO2Sulfur doped TiO2Visible-LightEscherichia-ColiTitanium-DioxideWaste-WaterNitrogenUvNanocatalystsDisinfectionSuspensionstext::journal::journal article::research article
