“…When fine crystalline S-doped TiO 2 was synthesized in the study of Ho et al [72] through a simple hydrothermal method, the optical absorption of S-doped TiO 2 in the visible light region increased in tandem with the increase in the S content. This may be related to the finding by Tian et al [71] that the anatase/rutile phase composition ratio was strongly influenced by the amount of S. The phase composition ratio increased with the increase in S amount, with TiO 2 doped with 1.5% S displaying the best crystallite size (around 30 nm).…”

This paper aims to review and summarize the recent works on the photocatalytic degradation of various organic pollutants in the presence of nano-doped-TiO 2 photocatalysts. In this regard, three main aspects are examined: (a) the presence of various dopants (metal dopants, nonmetal dopants, halogen dopants, metalloid dopants, and codopants) in the formation of nano-doped-TiO 2 photocatalysts, (b) the effect of the presence of dopants on the photocatalytic degradation of organic pollutants, and (c) the effects of various operating parameters on the photocatalytic degradation of organic pollutants in the presence of nano-doped-TiO 2 photocatalysts. Reports resulted suggest that the formation of a high percentage of the anatase phase, small crystallite size, and high specific surface area of the nano-doped-TiO 2 photocatalysts depends on the presence of various dopants in the photocatalysts. The majority of the dopants have the potential to improve the photocatalytic efficiency of nano-doped-TiO 2 in the degradation of organic pollutants. The photocatalytic degradation of organic compounds depends on the calcination temperature of the prepared doped TiO 2 , initial reactant concentration, dosage of doped TiO 2 , and dopant doping concentration.

TiO2 -SiO2 -In2O3 nanocomposite thin film was deposited on the glass substrates using a dip coating technique. The morphology, surface composition, surface hydroxyl groups, photocatalytic activity and hydrophilic properties of the thin film were investigated by AFM, XPS, methyl orange decoloring rate and water contact angle measurements. The hydroxyl content for TiO2, TiO2-SiO2 and TiO2-SiO2-In2O3 nanocomposite films was calculated to be 11.6, 17.1 and 20.7%, respectively. TiO2-SiO2-In2O3 film turned superhydrophilic after 180-min irradiation with respect to pure TiO2 and TiO2-SiO2 thin films. The photocatalytic decomposition of methyl orange for TiO2, TiO2-SiO2 and TiO2-SiO2-In2O3 thin films was measured as 38.19, 58.71 and 68.02%, respectively. The results indicated that SiO2 and In2O3 had a significant effect on the hydrophilic, photocatalytic and self-cleaning properties of TiO2 thin film.

“…Doping different elements into TiO 2 , including metal [8,9] and non-metal elements increases the photocatalytic efficiency [10,11]. Researchers indicated that N-containing [12] S-containing [13] or N-doping [14,15] S-doping [16] and N, S co-doping of TiO 2 can improve the visible light response [7].…”

Activated carbon (AC) loaded nitrogen and sulfur (N, S) co-doped TiO 2 nanomaterial (AC-N-STiO 2 ) was prepared by precipitation method. AC-N-S-TiO 2 material was characterized by Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray analysis (EDX), X-ray diffraction (XRD), Fourier Transform -Infrared (FT-IR), Photoluminescence (PL) and atomic force microscopy (AFM) analysis. Photodegradation and decolorization of Malachite green (MAG) and Methyl green (MEG) by using TiO 2, N-S-TiO 2 and AC-N-S-TiO 2 under UV-light irradiation has been carried out. The photocatalytic activity of the AC-N-S-TiO 2 was higher than that of the undoped and N, S-doped TiO 2 , The hydroxyl radical analysis -Fluorescence technique with coumarin has been discussed. The photodegradation of MEG was well described by analyzed to be pseudo-first order according to the Langmuir-Hinshelwood representation, the high quantum yield set up to be calculated, stability and reustability of nanomaterial. AC-N-S-TiO 2 act as a promising photocatalyst for dye wastewater treatment under UV-light irradiation.
