Synthesis and photocatalytic properties of Sn–TiO₂ nanomaterials

Abstract

Sn-doped TiO2 nanomaterials were synthesized by sol–gel method. It was shown the phase compositions and phase transitions change with the introduction of different tin amounts (0.5–20[Formula: see text]mol.%). X-ray powder diffraction was used to study the effect of different tin amounts on the anatase–rutile phase transition. It was found that the introduction of ions increases the thermal stability of anatase modifications. The material’s photocatalytic activity was studied in reaction with a model pollutant (methylene blue) photodegradation under UV and visible light activation. The best photocatalytic properties were shown for material, which contains 5[Formula: see text]mol.% of Sn.

One‐dimensional electrospun ceramic nanomaterials and their sensing applications

“…From the onset, the conductive fibers, which were prepared via electrospinning, exhibited nanometer-and centimeterlevel diameters and ultralong lengths, respectively. 20 Subsequently, researchers employed different approached to modify the various unique characteristics, such as conductivity, [36][37][38][39] photocatalysis, [40][41][42][43] luminescence, 44 magnetism, 40,45,46 and energy storage, 17,47,48 of the nanofibers.…”

Synthesis and Characterization of Various Doped TiO2 Nanocrystals for Dye-Sensitized Solar Cells

“…investigated the various properties of Sn-TiO 2 nanoparticles prepared by the sol–gel process. With the variation of the dopant concentration, they noticed the corresponding change in the phase compositions and phase transitions; however, anatase-TiO 2 was found thermally stable and showed the better photocatalytic activity with the nanoparticles obtained with the 5 mol % concentration of Sn . In another study, Mehraz et al reported the preparation and characterization of tin-doped TiO 2 aggregates.…”

Characteristics of Doped TiO2 Nanoparticle Photocatalysts Prepared by the Rotten Egg White

“…However, a new type of element-doped TiO 2 photocatalyst was prepared using sol-gel method, and this study also analyzed the mechanism of TiO 2 photocatalysis, examined related preparation methods, and investigated methods by which to improve its photocatalytic activity, such as doping and compounding, with the aim of further expanding the application of TiO 2 photocatalysis in the future. The sol-gel preparation method used in this work is popular because it is simple, less time-consuming than other methods, and operates under normal atmospheric temperature, and the process of synthesizing nanomaterials is easy and convenient [6,17,18]. The new F-doped TiO 2 photocatalytic catalyst prepared in this work was tested under UV-visible irradiation and in MB photo reactivity experiments, and it was found to have a good reaction effect in the visible light range.…”
