Mn doped ZnO nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. Mn doped ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photo-reduction activity of photocatalyst was evaluated using an azo textile […]
ZnO and SnO2-doped ZnO nanoparticles were prepared by a sol–gel method for the first time. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the ZnO and SnO2-doped ZnO samples. Advanced oxidation processes (AOPs) have proved very effective in treatment of the various hazardous organic pollutants such as surfactants and pharmaceuticals in […]
This study was aimed at investigating the photocatalytic degradation of ciprofloxacin (CIP) antibiotic in aqueous solution using immobilized ZnO nanoparticles on glass plate. X-ray diffraction, atomic force microscopy, and scanning electron microscopy were applied to characterize the nanoparticles. To do so, the ZnO nanoparticles were synthesized through the chemical precipitation method and were immobilized on […]
In the present study, silver-doped TiO2 (Ag/TiO2) nanoparticles were prepared by various Ag doping (wt%) and a combination of sol-gel and ultrasound irradiation. Ag/TiO2 nanoparticles were characterized by energy-dispersive X-ray analysis (EDX), scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. Based on the Taguchi method, photocatalytic degradation of (Reactive Blue 255) RB 255 azo […]
ZnO and 2% Fe doped ZnO photocatalytic nanomaterials were successfully synthesized by successive ionic layer adsorption and the reaction (SILAR) method. The characterizations of these nanomaterials were carried out using XRD, SEM and EDX techniques. XRD study shows that the samples have a hexagonal wurtzite crystal structure, size of which is in the range 21-23 nm. […]
Zinc Oxide nanoparticles (ZnONPs), which have well-known antimicrobial properties, are used extensively in various medical and general applications. In this analysis, 70-gram positive bacterial isolates were obtained from 100 patients using cardiac catheterization, with 54 Staphylococcus aureus and 16 other positive pathogenic bacteria. Accordingly, morphological, cultural and biochemical testes confirmed the results by VITEK 2 […]
Fe-doped TiO2 nanoparticles were successfully synthesized by the coprecipitation method. TiO2 was doped with a different molar ratio of iron amounts, namely 0.1% and 0.2%. An undoped TiO2 was also prepared for comparison. X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV-visible diffuse reflectance spectroscopy techniques were used to characterize the as-synthesized nanoparticles. The XRD […]
One of the foremost inescapable impediments that industrial sectors face is to remove organic pollutants, which affected nature and threatened the existence of species per se. Nanoscale magnetic ferrites are considerable materials for removing the majority of organic dyes due to their unique properties and high potential photocatalytic activity. Their photocatalytic performance in semiconductor nanocrystals […]
