“…Industrial dyestuffs are one of the organic pollution sources of wastewater pollution and represent an increasing environmental hazard [1]. It is a kind of chemically stable, nonbiodegradable, and difficultly decomposed dye pollutant in wastewater that are continuously emitted into the environment from various dyestuff and textile industries [2].Consequently, different strategies have been devised for treatment of wastes containing persistent organic materials.…”

Pure tetragonal zirconia nanosheets were successfully prepared by modified Pechini method. In this approach, ZrOCl 2 .6H 2 O, tri ethanol amine (TEA) and citric acid (CA) were used as the source of Zr 4+ , the chelating and polymerization agent, respectively. The effects of heat treatment and TEA:CA: Zr 4+ ratios on the structure, morphology and zirconia particle size were investigated.The microstructure of the products was characterized by X-ray diffractometry (XRD), thermogravimetric analysis (TGA) scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) analysis. The zirconia nanosheets exhibit photoluminescence at room temperature with a broad emission in the blue region of the visible spectrum. Finally, the effect of calcination temperature on the photocatalyst properties of nanosheets was investigated.

The photocatalysts Bi 2 O 3 :Ce 3 + /Ce 4 + (cerium content 0.2, 0.5, 0.8, and 1.1 wt. %) were prepared via one-pot ethylene glycolassisted solvothermal method. The prepared x Ce-Bi 2 O 3 (x = 0.5, 0.8, 1.1) samples present δ-Bi 2 O 3 phase with space group of Fm-3 m at room temperature, which indicates that the hightemperature cubic phase could be stabilized via Ce doping in Bi 2 O 3 lattices. Moreover, the addition of Ce 3 + /Ce 4 + could change the amount of oxygen vacancies (OVs) and adsorbed oxygen on the surface of photocatalysts. The existence of oxygen vacancies and adsorbed oxygen facilitated the generation of superoxide radicals () and hydroxide radicals (), which were the dominant reactive oxygen species for phenol degradation. The photocatalyst containing 0.8 wt. % cerium presented the highest photoactivity than the other synthesized samples. A photodegradation mechanism is proposed based on scavenger and electron spin resonance studies.[a] T.
