“…Discharge of inorganic and organic pollutants from varying industries including printing, textiles, food, and beauty products into environmental water resources has been a main environmental problem in all countries regardless of how they are developed. Up to date, different methods based on physical, chemical, and biological treatments such as membrane processes, reverse osmosis, photocatalytic degradation, photo-Fenton, ozonation, oxidation, biological, as well as electrochemical procedures have been used for remediation of industrial wastewaters (Barbusiński, 2005;Farré et al, 2005;Liu et al, 2007;Dogan and Turkdemir, 2012;Ioannou et al, 2013;Zheng et al, 2013;Suresh et al, 2014;Suresh et al, 2016;Jesudoss et al, 2017;Rajan et al, 2017;Kooshki et al, 2019;Peymani-Motlagh et al, 2019a;Peymani-Motlagh et al, 2019b;Rahimi-Nasrabadi et al, 2019;Sobhani-Nasab et al, 2019aSobhani-Nasab et al, 2019c). Among the most commonly mentioned methods which are subject to restrictions, photocatalytic degradation systems act as a smart tool, because it is simple, highly efficient, and inexpensive (Basith et al, 2014;Vijaya et al, 2017;Sedighi et al, 2018;Eghbali-Arani et al, 2018;Sobhani-Nasab et al, 2019d).…”

The new nanocomposite with various molar ratios along with magnetic properties was fabricated via precipitation (assisted by ultrasonic) procedure. The photocatalytic effects of methylene blue (∼90% degradation for optimized sample in 100 min) for finding the optimized sample performed under visible light irradiation. Moreover, the photo-antibacterial impacts of bacteria culture environments were found with an optimized sample that had effective destruction of bacteria in comparison to control group. The cytotoxicity properties of panc1 cells and magnetic behaviors of the obtained nanomaterials were evaluated and its IC50 was about 500 mg/L. As an initial step, the structural, morphological and magnetic characteristics of the fabricated nanocomposites were evaluated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) and MAP, UV-visible diffuse reflectance spectroscopy (DRS), and vibrating sample magnetometry (VSM) approaches. Based on SEM results, the size of nanoparticles in fabricated nanocomposite was nearly 50-70 nm for Fe 3 O 4 /SiO 2 /TiO 2 and 80-100 nm for Fe 3 O 4 /SiO 2 /TiO 2 /CeVO 4 . XRD results showed that desired nanocomposites were truly synthesized without any impurities.

“…[11b,13] Secondly, the doping Re ions may cause surface oxygen vacancies and defect states of the photocatalyst. [14,15] Followed these two theories, several typical Re-doped Bi 2 WO 6 nanomaterials were prepared and applied for dye photodegradation, the results (Table 1) indicated that the photodegradation ability of the nanocomposites under visible-light irradiation was better than that of pure Bi 2 WO 6 . We selected the Gd element because the ionic radius of Gd 3 + (0.938 Å) is smaller than that of Bi 3 + (1.03 Å).…”

Bi 2-x Gd x WO 6 /rGO was prepared by a two-step process. Firstly, Bi 2À x Gd x WO 6 (BGWO-x) nanomaterials were synthesized via a hydrothermal method, and then BGWO-x was homogenously implanted as a filler into the rGO nanosheets to obtain a novel 3D porous composite. The physical-chemical properties were investigated by X-ray diffraction, UV-vis diffuse reflectance spectroscopy, scanning electron microscopy, transmission electron microscopy, energy dispersive spectrometry, photoluminescence spectroscopy, X-ray photoelectron spectroscopy and N 2 adsorption-desorption isotherm analysis. The photocatalytic activity of samples was envaulted by degrading three organic dyes (rhodamine B (Rh B), methyl orange (MO), and methylene blue (MB)) under visible-light irradiation (300 W mercury lamp). Doping of Gd 3 + ions could reduce the bandgap of Bi 2 WO 6 , thus improving its light absorption range. The BGWO-0.25 with the best photocatalytic performance was selected to construct the BGWO-0.25/rGO (BGWO/G) nanocomposite, which exhibited the excellent synergistic effect of adsorption-enrichment and photocatalytic degradation. The removal rates of Rh B, MB, and MO by BGWO/G were about 1.96, 2.94, 2.82 times as that of the pure Bi 2 WO 6 . And the proposed mechanism of photocatalytic degradation was deduced, in which the photogenerated O 2 * À and h + (active species on the surface of BGWO/ G) played the roles of active species during the reaction.

“…These radiations reduce the efficiency and performance of electronic instruments and thus decrease their lifetime and safety. As MnZn ferrite belongs to the class of soft ferrites having high electrochemical stability, high permeability, high saturation magnetization and low power losses, it is used in many electronic applications [65,79,128,167,199,209,210].Ferrite nanoparticles can be used in the radar absorbing devices due to their high value of curie temperature and temperature stability. Also the ferrite nanoparticles are environmentally safe that make their use easier in the radar absorbing devices.…”
