a new approach for the synthesis of prussian blue nanoparticles using the cationic surfactant cetyl pyridinium chloride (cpc) as capping agent has been developed in the present work. powder x-ray diffraction, transmission electron microscopy, uv–vis absorption spectra, and ir spectroscopy were employed to characterize the product. the tem image showed that the prussian blue nanoparticles with d...

CeO2/ZnO nanocomposites were synthesized by microwave method that is the fast process. One of an eco-friendly solvent, ethylene glycol were used the effect of time and power of irradiation were investigated on morphology and size of nanoparticle. Prepared CeO2/ZnO nanocomposites are characterized with X-ray diffraction (XRD) analysis, Transmission Electron Microscopy (TEM), Fourier Transform In...

Copper-manganese oxide catalysts are prepared with an atomic ratio of Cu/Mn=2/1 using a coprecipitation procedure under air atmosphere. The time of aging, i.e., the time that precipitate remains in contact with the precipitating medium, has been varied from 0 (for unaged precursor) to 300 minutes and the effect of precipitate aging time in each atmosphere upon the structure and morphology of di...

In this study, green or eco-friendly synthesis of TiO2 nanoparticles (NPs) was performed by using the aqueous extract of Acanthophyllum laxiusculum. The plant genus Acanthophyllumis one of the natural sources rich in nonionic surface active agents known as saponins. Sol-gel method as one of the most common techniques widely used in nano-field was applied to synthesize the titanium dioxide nanop...

In this work, we report synthesis and characterization of Bi2O3 nanoparticles loaded on mesoporous MCM-41 nanoparticles by a simple solid-state dispersion (SSD) method. Monoclinic bismuth oxide nanoparticles were prepared by polyacrylamide gel method and used as loading materials on the prepared mesoporous MCM-41 as a supporting material. Fourier transform infrared spectroscopy (FT-IR), X-ray p...

a new sorbent composed of 3-aminopropyltriethoxy-silane-coated magnetic nanoparticles, functionalized with rhodium(iii) porphyrin complex was synthesized and characterized by elemental analysis, x-ray diffraction (xrd), transmission electron microscopy (tem), fourier transform infrared spectroscopy (ft-ir) and thermogravimetric analysis (tga). the effect of some co-existing anions present in aq...

tm3+, yb3+ and tm3+/yb3+ doped lavo4 nanostructures were synthe-sized for the first time by using the hydrothermal method with the aid of la(ch3co2)3 as  lanthanum source in presence of oleic acid as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), photoluminescence (pl) spectroscopy and uv–vis di...

Herein, the removal of methyl orange (MO), a monoazo dye, from aqueous solutions was investigated using bimetallic ferromagnetic Fe/Ni nanoparticles (NPs) with the average particle size of 12-16 nm. The effect of contact time, pH, temperature, and Fe/Ni dosage on dye removal process was investigated. The results showed that 60 mg of Fe/Ni NPs at 25 oC and pH= 1 can remove 99.5% of 50 mg/L dye s...

Green biosynthesis of silver - functionalized multiwalled carbon nanotube (Ag/FMWCNT) nanohybride from silver nitrate solution using water extract of Satureja hortensis L as reducing agent and FMWCNT as anchoring agent at room condition was succesfully carried out. Water-soluble organics present in the plant materials were mainly responsible for the reduction of silver ions to nano-sized Ag par...
