Controlled photocatalytic degradation of basic red 46 in textile industrial wastewater with the aid of N–S codoped TiO2 (NSTO)

In the current study, barium molybdate (BaMoO 4 ) nanostructures were synthesized via a largescale and facile sonochemical method based on the reaction between barium(II) nitrate hexahydrate and (NH 4 ) 6-Mo 7 O 24 Á4H 2 O in an aqueous solution. Besides, two amino acids leucine and proline were introduce as capping agents and their effects on the morphology and particle size of barium molybdate were investigated. It was found that size and morphology could be easily realized by changing the type of amino acids. XRD, SEM, EDS, and UV-Vis spectroscopy were employed to characterize structural, morphological, and optical properties of BaMoO 4 nanostructures. Barium molybdate (BaMoO 4 ) nanostructures indicated a ferromagnetic behavior at room temperature, as evidenced by using vibrating sample magnetometer. Furthermore, the photocatalysis results reveal that the maximum decolorization of 75 % for methyl orange occurred with BaMoO 4 samples in 70 min under ultraviolet light irradiation.

“…Various physical and chemical methods have been used for color removal from waste waters. One of these methods is semiconductor photocatalysis and it has proven to be an effective in treating waste water pollution since it is an environmentally friendly, low-cost, and sustainable treatment methodology [9][10][11][12][13]. The search for low cost and efficient photocatalysts is still continuing.…”

In this work, we have successfully prepared lutetium doped copper ferrite nanoparticles through green approach by utilizing of copper nitrate, iron nitrate, lutetium nitrate and starch in an aqueous solution. Starch plays role as capping agent, reductant agent, and natural template in the synthesis CuFe 2-x Lu x O 4 nanoparticles. The as-prepared CuFe 2-x Lu x O 4 nanoparticles were characterized extensively by techniques like XRD, SEM, UV-Vis, and EDX. The magnetic properties of as-prepared CuFe 2-x Lu x O 4 nanoparticles were also investigated with vibrating sample magnetometer. In addition, methyl orange was chosen as a dye water pollution to evaluate its degradation by as-synthesize CuFe 2-x Lu x O 4 under ultraviolet light irradiation. The photocatalysis results reveal that the decolorization of 65 % for methyl orange occurred with CuFe 2-x Lu x O 4 nanostructures in 70 min under ultraviolet light irradiation.

“…Besides, several experiments were performed in order to investigate the effect of different surfactants such as sodium dodecyl benzene sulfonate (SDBS), sodium dodecyl sulfate (SDS), and polyethylene glycol (PEG) on the morphology, particle size, and crystal structure of final products. Moreover, the photocatalytic degradation was investigated using methyl orange (MO) under ultraviolet light irradiation to study the photocatalytic activity of as-prepared nanoparticles [29][30][31][32].…”

In this paper, cadmium tungstate (CdWO 4 ) nanoparticles were synthesized via a precipitation method based on the reaction between cadmium nitrate hexahydrate and sodium tungstate dihydrate in water. Besides, three surfactant agents such as sodium dodecyl benzene sulfonate, sodium dodecyl sulfate, and polyethylene glycol were used to investigate their effects on the morphology and particle size of CdWO 4 nanoparticles. According to the vibrating sample magnetometer, cadmium tungstate (CdWO 4 ) nanoparticles indicated a ferromagnetic behavior at room temperature. To evaluate the catalytic properties of nanocrystalline cadmium tungstate, the photocatalytic degradations of methyl orange under ultraviolet light irradiation were carried out. The structural, morphological, magnetic, and optical properties of as-obtained products were characterized by techniques such as XRD, SEM, EDX, VSM, and UV-Vis spectroscopy.
