TL;DR: In this paper, ground fly ash (GFA), with a median particle size of 10.5μm, was used as source material for making geopolymers cured at room temperature, and compressive strength tests and microstructure observations using SEM, EDX, XRD and FTIR were performed.

TL;DR: In this article, a review focusing on the heterogeneous photocatalytic treatment of organic dyes in air and water is presented, which includes historical aspects, dark adsorption of the dye on the semiconductor surface and its role in the subsequent photoreaction, semiconductor preparation details, photoreactor configurations, photooxidation kinetics/mechanisms and comparison with other Advanced Oxidation Processes (e.g., UV/H 2 O 2, ozonation, UV/O 3, Fenton and photo-Fenton reactions), visible light-

TL;DR: Diethanolamine provided the highest visible light absorption ability of interstitial N-doped TiO(2) with the smallest energy bandgap and the smallest anatase crystal size, resulting in the highest efficiency in 2-chlorophenol degradation.

TL;DR: In this paper, a sol-gel technique with dip coating method is used to prepare photocatalytic TiO2 thin films immobilized on glass plates and the structure and morphology of thin films are characterized by X-ray diffraction and scanning electron microscope (SEM).

TL;DR: In this paper, the relationship between the morphology of anodic tungsten(VI) oxide (WO 3 ) layers and their subsequent photoelectrochemical response in 0.5 m Na 2 SO 4 supporting electrolyte was investigated.
