Zinc oxide (ZnO) and ZnO/CdS nanoparticles have been synthesized. The samples were characterized by Fourier transform infrared spectroscopy (FT–IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Photocatalytic reduction of toxic Hg (II) in aqueous solutions by suspension ZnONPs and ZnO/CdSNPs has been studies under an oxygen atmosphere. Flame atomic absorption (AFM) has been used […]
The main purpose of this study was to investigate the photocatalytic decomposition of the antibiotic Cefazolin (CFZ) from aqueous solutions using a new effective catalyst. This catalyst was made of α-Fe2O3-supported nanoparticles on a metal-organic framework (MOF). The synthesis of Nano α-Fe2O3 photocatalyst was performed by the reflux condensation method. The MOF was synthesized using […]
Chemical bath deposition (CBD) was used to prepare titanium dioxide (TiO2) nanocrystalline thin films on glass substrates. The TiO2 nanocrystalline thin films were created, and the Scanning Electron Microscope (SEM) images showed that they developed as nanoflowers and tiny semi-nanoplate bundles that grew vertically onto the surface of the substrates with uniform distribution. The nanoplate […]
Both metal oxides, ceria (CeO2) and stania (SnO2) are prepared by precipitation technique using ammonia solution (1:1) and characterized by thermogravimetric analysis (TGA), x-ray powder diffraction (XRD), transmission electron microscope (TEM), nitrogen adsorption-desorption (for the specific surface area determination, SBET) and used in the photodegradation of Tenoxicam (TEN) antibiotics by using ultraviolet irradiation in presence […]
In this study, a simple technique was used for synthesizing one-dimensional ZnO/Fe2O3/Fe3O4 nanostructures (NSs) through heat treatment under vacuum by using a magnetic field at a temperature of 200 °C for 1 h. The photocatalytic effect of the NSs were studied by decomposing methyl orange (MO) dye (5 mg/L, pH = 8.1) under ultraviolet illumination. […]
A series of bismuth-silicate photocatalysts were synthesized via the sol-gel method for photodegradation of methylene blue (MB) under sunlight irradiation, utilizing rice husk ash as a silica precursor. The scanning electron microscopy/energy dispersive X-ray (SEM/EDX) analysis detected Bi content in 3-10 wt% range. Furthermore, it can be seen that the porosity decreased as the Bi […]
