| In various advanced oxidation processes, photocatalysis is a promising and efficient way? to remove natural organic matter consisting of humic acids and fulvic acids. The princple of this method involves both usage of a semiconductor photocatalyst and O2 for the generation of radicals. Among them, TiO2 photocatalysis is the most popular and studied onesince TiO2 has unique properties such as being chemically inert, photocatalytically stable,cheap, non-toxic, environmentally benign and exhibiting high oxidative power. However,despite all the advantages of using TiO2 as a photocatalyst, there is a major disadvantage.Since TiO2 has a broad band gap, its usage widely under solar light is limited and only allows to be active under UV light. Doping is one of the most popular methods to enhancethe photocatalytic activity of TiO2 via using metal or non-metal species as dopants. Inthis respect, solar light sensitive TiO2 photocatalyst, C, N, S, Se doped and S/N codopedTiO2 photocatalysts were synthesized by using wet-impregnation method. These dopedphotocatalysts were characterized by Raman spectroscopy to determine the crystal surfacemorphology. Moreover, methylene blue was used to investigate the photocatalytic performance of prepared doped TiO2 photocatalysts in the presence or absence of organic matrix.Photocatalytic experiments were performed using a solar light simulating photoreactor.Humic acid characterization was monitored by UV-vis and fluorescence spectroscopy. |
