In this study, we aimed to observe how different operating parameters influenced the photocatalytic degradation of rhodamine B (RhB, cationic dye) and bromophenol Blue (BPB, anionic over ZnO/CuO under visible light irradiation. This further corroborated optimization study employing response surface methodology (RSM) based on central composite design (CCD). The synthesis nanocomposite was carrie...

Antidepressants are one of the main pollutants in aquatic environment. They being widely studied due to their widespread use, possible health effects, and partial removal from wastewater treatment plants by conventional methods. Photocatalysis is an effective ecologically beneficial method treatment. In present study, photocatalytic degradation sertraline hydrochloride (SERT) water using nano-s...

Photoreactivity of cadmium sulfide nanoparticles as undoped and doped with manganese, nickel and copper were studied in the decolorization of methylene blue and safranin under UV and Vis irradiations. The dopant, mole fraction of dopant to cadmium ion, pH of solution, dosage of photocatalyst and concentration of dye are variables that influence on the photoreactivity of nanocatalysts. In among ...

Combination the non-thermal plasma technique by photocatalytic oxidation can enhance volatile organic compounds degradation. In this study, the decomposition of chloroform vapors in a novel non-thermal plasma reactor as well as an integrated system of this reactor in conjunction with the photocatalysis process was investigated. Expanded graphite was used as discharge electrode of dielectric bar...

Background & Aims of the Study: Malachite Green (MG) is the most commonly used substance for dying cotton, food & pharmacy industries, paper, leather and silk. On inhalation it can cause difficult breathing, while on the direct contact it may cause permanent injury of the eyes of human and animals, burning sensations, nausea, vomiting, profuse sweating, mental confusion and met...

s-doped and bare mesoporous tio2 were prepared using titanium tetraisopropoxide and thiocarbamide as raw materials. prepared materials were characterized by means of fourier transform infrared spectroscopy ft-ir, thermogravimetry-differential scanning calorimetry (tg-dsc), x-ray diffraction (xrd), uv–vis absorption spectroscopy, brunauer–emmett–teller (bet) specific surface area and barrett–joy...

in this research fe-tio2 nanocomposites with different molar ratios of fe/ti were prepared as nano-photocatalyst using a modified sol-gel process at ambient temperature. crystallographic properties of nanocomposites were characterized by x-ray diffraction (xrd). surface morphology and mean particle size of nanocomposites were specified by field emission scanning electron microscopy (fesem) and ...
