This work describes the simplest method of synthesis of a carbonized cobalt catalyst based on an available natural mineral, clay activated with nitric acid, which showed high selectivity and activity in hydrogenation of acetylene to ethylene. Metal catalysts with cobalt contents of 5 %-7 % in a bentonite clay carrier from the Tonkeris deposit were […]
Titanium dioxide nanotubes TNTs were synthesized by anodization in a fluoride-based electrolyte, TNTs are commonly working as photocatalytic under ultraviolet UV irradiation via its wide bandgap, and it was expanded under visible light irradiation by doping with other metals or metals oxides, herein TNTs were doped by copper oxides Cu2O and CuO to produce copper […]
The results of studies on obtaining and characterization of silver nanoparticles aqueous solution under the action of the contact non-equilibrium low-temperature plasma and stabilizing agent (sodium citrate) are presented in the paper. The influence of the basic parameters on the synthesis of silver nanoparticles was studied. Different physicochemical characteristics were investigated: initial precursor concentration, reagent […]
Porous ZnO-hydroxyapatite nanocomposite was prepared by dissolution of a rock phosphate ore in an acidic medium followed by alkaline precipitation. Its photocatalytic activity was assessed for the degradation of paracetamol as one of the most commonly prescribed pharmaceutical drugs and methylene blue as dye model. Thanks to its good porosity, the 40ZnHAp nanocomposite adsorbed the […]
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 goal of this research is to create nanostructured metal free phosphorous doped Boron nitride (P-BN) and phosphorous-carbon co-doped Boron nitride (CP-BN) that serve as photocatalysts when exposed to UV light. P-NPs were well diffused in aqueous solution. The nanostructured materials were characterized using XRD, SEM-EDX, and UV-Vis spectrophotometry. Based on the characterization results, phosphorous […]

The applications of photocatalytic nanomaterial technology received intense scientific focus with the advent of nanotechnology. Applications based on TiO2 nanoparticles have shown promise of photocatalytic efficiency among many semiconductor metal oxides. Titanium dioxide is utilized in many practical applications such as water and air purification, self-cleaning of surfaces, and energy production. The major drawback with […]
Here, SnO2, BiVO4, and CuO nanoparticles (NPs) were hydrothermally synthesized and mixed in an agate mortar mechanically. The coupled ternary SnO2-BiVO4-CuO (SBC) catalyst and the individual NPs were then briefly characterized by powder X-ray diffraction (XRD), scanning electron microscope (SEM), and diffuse reflectance spectroscopy (DRS). Average crystallite size of 25 nm was obtained from the […]
In this study, Ag and Pd nanoparticles (NPs) were immobilized on natural zeolite and magnetized zeolite (Fe3O4/natural zeolite) by using an aqueous Chrysanthemum morifolium flower extract, as a green and low-cost method. Different techniques such as FTIR, XRD, FESEM, EDS, and VSM were used for the characterization of prepared nanocomposites. The FESEM and TEM images […]
