It’s fascinating to see how much research has been done on ferrite nanoparticles over the past few years. These small magnetic particles have unique properties that allow them to be manipulated at a very small scale. This review article is focused on the preparation of ferrite magnetic nanoparticles and silica-coated ferrite nanoparticles using various functionalized […]
In this study, we synthesized ethyl levulinate (EL) by alcoholysis of furfuryl alcohol (FAL) with ethanol using two catalysts, SBA-15-SO3H (SHS-15) and SBA-16-SO3H (SHS-16). The catalysts were prepared through the hydrothermal method, and their physical and chemical properties were assessed using various techniques such as small and wide-angle XRD, N2-sorption, SEM, TEM, FTIR, and Py-FTIR. […]
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 research, a novel approach for the epoxidation of alkene derivatives was constructed. Based on this fact, the appropriate ligand was provided from the reaction of hydrazine hydrate and 5-methyl-1,3,4-thiadiazole-2-thiol. Then, after preparation of the intermediate compound, the treatment of the pointed compound and 4-hydroxy-3,5-dimethoxybenzaldehyde in the presence of a few drops of glacial […]
The sol-gel technique is employed for the synthesis of tungsten trioxide (WO3) nanosheets. The Au/WO3 nanocomposite is prepared using laser ablation employing an Nd-YAG laser operating at a wavelength of 1064 nm and utilizing gold metal. The SEM images demonstrate that WO3 was formed as nanosheets with a thickness between 36nm and 80nm. X-ray diffraction […]
Lanthanum (III) oxide (La2O3) was applied as an efficient bifunctional catalyst to develop a new methodology in the production of 2-amino-4-aryl-4H-pyrans and pyrazolopyranopyrimidines in the absence of solvent. In both synthetic protocol, due to the dual functionality of lanthanum (III) oxide (i.e. having basic and acidic Lewis sites), it was very useful and general, and […]
The synthetic dyes which are largely used in the textile industries pollute the total ecosystem. They can be treated using different technologies but in order to avoid secondary pollution and to carry out an eco-friendly technique, an electrocoagulation process has been adopted. In this work, two sets of electrodes which act as the electrocatalysts for […]
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 […]
