The aim of the present work was to evaluate effectiveness a heterogeneous photocatalyst based on TiO2 in treatment coal mining drainage which contains variety heavy metals and high concentration sulfates sulfides. photocatalytic behavior commercial reference Sigma Aldrich different materials synthesized using Sol-gel methodology with surface modifications sulfation fluorination processes were a...

reactions of free radicals and reactive oxygen species (ros) with biological molecules in vivo play an important physiological role in many diseases. 2,2-diphenyl-1-picrylhydrazyl (dpph) is a stable free radical and often used as a routine reagent to evaluate the antioxidant capacity of an antioxidant. this study was undertaken to investigate the free radical-scavenging and antioxidant activiti...

Absorption spectra of several free base triarylcorroles were investigated by MCD spectroscopy. The MCD spectra exhibit unusual sign-reverse (positive-to-negative intensities in ascending energy) features in the Soret- and Q-type band regions, suggesting a rare ΔHOMO < ΔLUMO relationship between π and π* MOs in the corrole core.

The paper presents a modification of titanium dioxide with fumed silica. SiO2/TiO2 photocatalysts were obtained by the sol-gel method and then calcined under an argon atmosphere. Various SiO2 weights (2–17.2 wt.%) used in materials’ preparation stage. samples characterized using advanced analytical methods, such as FT-IR/DRS infrared spectroscopy, X-ray diffraction, SEM scanning electron micros...

In this work, an SrSnO3/g-C3N4 heterojunction with different dosage of SrSnO3 was fabricated by ultrasound-assisted hydrothermal approach and characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), photoelectron (XPS), scanning electron microscopy (SEM), transmission (TEM), UV-visible diffuse reflectance spectra (UV-Vis DRS), photoluminescence (PL). Ciprofloxacin ...

Sphere-like cadmium molybdate (CdMoO4) nanostructures have been synthesized by a large scale and simple sonochemical method by using Cd(Sal)2 (Sal=salicylidene) and Na2MoO4.2H2O for the first time. The effects of sonochemical irradiation time, sonochemical power, temperature, solvent, surfactant and cadmium source were considered to obtain a controlled shape. The as-prepared nanostructured cadm...

In recent years, green synthesis of nanoparticles has attracted a great attention because of medicine and biological applications. In this work, bismuth oxide nanoparticles (Bi2O3 NP) was prepared via green synthesis using mentha pulegium aqueous extract after 24 h at 90°C. The product was characterized by ultraviolet-visible (UV-VIS) spectrophotometer, Fourier transform infrared (FTIR), X-ray ...
