The degradation of methyl tert-butyl ether (MTBE) was investigated in the aqueous solution coated ZnO onto magnetite nanoparticale based on an advanced photocatalytic oxidation process. photocatalysts were synthesized by coating using precipitation method. sample characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibration magnetometer (VSM). Besides, specific surface area also determined BET four effective factors including pH reaction mixture, Fe3O4/ZnO magnetic...
In this study, the performance of an aerobic moving bed biofilm reactor (MBBR) was assessed for removal phenol as sole substrate from saline wastewater. The effect several parameters namely inlet concentration (200–1200 mg/L), hydraulic retention time (8–24 h), salt content (10–70 g/L), shock loading, loading and on 10 L MBBR inoculated with a mixed culture active biomass gradually acclimated to were evaluated in terms chemical oxygen demand (COD) efficiencies. results indicated that COD...
A CuO-ZnO@graphitic carbon nitride (Cu/Zn/g) triplex heterojunction nanocomposite was prepared through a multistep ultrasound-assisted hydrothermal procedure. XRD, SEM, EIS, EDX, BET, FT-IR, EDS, UV–Vis, TEM, PL, and transient photocurrent techniques were employed for catalyst characterization. The XRD profiles demonstrated the formation of ZnO wurtzite phase CuO monoclinic in samples. It revealed by SEM TEM images that Cu/Zn/g is composed g-C3N4 nanosheets decorated with nanorods...
The photocatalysis of phenol was studied using Fe3O4/ZnO core/shell magnetic nanoparticles (MNPs). photocatalysts were synthesized by coating ZnO onto the magnetite precipitation method and characterized XRD, SEM FTIR measurements. Using Taguchi method, this study analyzes effect parameters such as calcinations time, temperature molar ratio Fe3O4:ZnO on photo activity MNPs. XRD analysis confirm that process done successfully. images show average particle size about 50 nm. removal efficiency...
In this study the optimum conditions for preparing iron-doped TiO2 nanoparticles were investigated. Samples synthesized by sol-gel impregnation method. Three effective parameters optimized using Taguchi method, consisted of: (i) atomic ratios of Fe to Ti; (ii) sintering temperature; (iii) time. The characterization samples was determined X-ray diffraction, BET- specific surface area, UV- Vis reflectance spectra (DRS) and scanning electron microscope (SEM). XRD patterns indicated existence...
The magnetic properties of MS (M = Li, Na, K) compounds in a Wurtzite structure at zero pressure are investigated by using first principle calculations and the pseudopotential self-consistent method based on density functional theory. It is shown that half-metallic ferromagnets with moment μ B per formula unit gaps 0.24, 0.52, 0.62 eV for LiS, NaS, KS, respectively. We also consider effect half-metallicity these we find KS maintain their up to lattice compressions 9%, 37%, 60%, respectively,...
