Effects of F- Doping on the Photocatalytic Activity and Microstructures of Nanocrystalline TiO2 Powders
TL;DR: In this article, a novel and simple method for preparing highly photoactive nanocrystalline F-doped TiO2 photocatalyst with anatase and brookite phase was developed by hydrolysis of titanium tetraisopropoxide in a mixed NH4F−H2O solution.
Journal ArticleDOI
The Effect of Calcination Temperature on the Surface Microstructure and Photocatalytic Activity of TiO2 Thin Films Prepared by Liquid Phase Deposition
TL;DR: In this article, a liquid-phase deposition (LPD) method was used on fused quartz by the liquid phase deposition method from a (NH4)2TiF6 aqueous solution upon addition of boric acid (H3BO3) and calcined at various temperatures.
Journal ArticleDOI
In situ construction of g-C3N4/g-C3N4 metal-free heterojunction for enhanced visible-light photocatalysis.
TL;DR: It is demonstrated that rational design and construction of isotype heterojunction could open up a new avenue for the development of new efficient visible-light photocatalysts and the removal of NO in air.
Journal ArticleDOI
Sulfur-doped g-C3N4 with enhanced photocatalytic CO2-reduction performance
TL;DR: In this article, a sulfur-doped graphitic carbon nitride (g-C 3 N 4 ) was fabricated by simply calcinating thiourea at 520°C, and it was found to absorb light up to 475nm corresponding to a band gap of 2.63 eV.
Journal ArticleDOI
Review on the improvement of the photocatalytic and antibacterial activities of ZnO
TL;DR: In this paper, a review of the application of photocatalytic degradation and the antibacterial properties of zinc oxide (ZnO) nanomaterials is reviewed, and the main methods that improve antibacterial activities are coating inorganic or organic antimicrobial agents, doping ZnO, and tuning the size, morphological characteristics, and concentration of ZnOs.
