“…Fe 2 TiO 5 nanoparticles were synthesized by a modified sol-gel method using Fe(NO 3 ) 3 • 9H 2 O and Ti(OCH(CH 3 ) 2 ) as starting reagents, oxalic acid as a chelating agent and CTAB as a surfactant. Details of the synthesis procedure are described in [16]. The obtained powder was calcined at 750°C for 3 h to obtain the desired Fe 2 TiO 5 nanoparticles.…”

The aim of this work was to synthesize semiconducting oxide nanoparticles using a simple method with low production cost to be applied in natural sunlight for photocatalytic degradation of pollutants in waste water. Iron titanate (Fe 2 TiO 5 ) nanoparticles with an orthorhombic structure were successfully synthesized using a modified sol–gel method and calcination at 750°C. The as-prepared Fe 2 TiO 5 nanoparticles exhibited a moderate specific surface area. The mesoporous Fe 2 TiO 5 nanoparticles possessed strong absorption in the visible-light region and the band gap was estimated to be around 2.16 eV. The photocatalytic activity was evaluated by the degradation of methylene blue under natural sunlight. The effect of parameters such as the amount of catalyst, initial concentration of the dye and pH of the dye solution on the removal efficiency of methylene blue was investigated. Fe 2 TiO 5 showed high degradation efficiency in a strong alkaline medium that can be the result of the facilitated formation of OH radicals due to an increased concentration of hydroxyl ions.

In this work, modify sol-gel method was used to synthesize nickel aluminate (NiAl 2 O 4 ) nanoparticles with aid of nickel nitrate hexahydrate and aluminium nitrate nonahydrate as the starting reagents in the presence of ethanol as the solvent. Besides, to examine the effect of different chelate agent such as citric acid monohydrate, oxalic acid, salicylic acid, and malic acid on the morphology and particle size of final products several tests were performed. The structural, morphological, and optical properties of as-obtained products were characterized by techniques such as Fourier transform infrared spectroscopy, X-ray diffraction, energy dispersive X-ray microanalysis, scanning electron microscopy and ultraviolet-visible. The photocatalytic degradation was investigated using methyl orange under visible light irradiation (k [ 400 nm). The resulting degradation rates of the methyl orange were measured to be as high as 90 % in 270 min.

In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and germs. Nowadays, nanostructures used for detection and removal of chemical and biological substances include metals, azo dyes, nutrients, cyanide, organics, algae, bacteria, parasites, and etc. In the current study, an attempt is made to synthesize and characterization of Ag dope PbTiO 3 nanoparticles in an aqueous environment through the twostep sol-gel method. Besides, glucose, lactose, and starch were applied as the natural capping agents and their effect on the morphology and particle size of final products were investigated by SEM analysis. The structural, morphological, and optical properties of as-obtained products were characterized by techniques such as XRD, SEM, EDX, and UV-Vis spectroscopy. In addition, in order to evaluate the photocatalytic properties of nanocrystalline Ag dope PbTiO 3 , the photocatalytic degradations of simulated methyl orange dye wastewater under ultraviolet light irradiation were carried out. Furthermore, the photocatalysis results reveal that the maximum decolorization of 74 and 66 % for methyl orange occurred with Ag dope PbTiO 3 and PbTiO 3 samples in 90 min under UV light irradiation, respectively.
