Plant-mediated synthesis of metal oxide nanoparticles is a promising alternative to the traditional method of physical and chemical synthesis. In this paper, we report the green synthesis of zinc oxide nanoparticles (ZnONPs) by a biological method. During the study, Zinc oxide nanoparticles were synthesized by Allium sativum skin (garlic skin) extract. Formation of zinc oxide nanoparticles has ...

ZnO is a semiconductor material that has important physical and chemical properties, which are frequently significantly enhanced by the addition of impurities, such as doping. A study structural properties pristine functionalized (i.e., doped with Antimony Tungsten) nanoparticles been conducted for photocatalyst-based degradation methylene blue (MB) dye under both Ultraviolet (UV) solar light. ...

Ta8(μ3-O)2(μ-O)8(μ-OEt)6(OEt)14 (1) was obtained by the controlled hydrolysis of tantalum ethoxide Ta(OEt)5 in the presence of ammonia. Compound 1 is considered as the intermediate building block in the sol-gel polymerization of Ta(OEt)5. Further hydrolysis of compound 1 yielded nanoparticles of Ta2O5, which were characterized by various techniques such as TGA-DTA-DSC, UV-vis DRS, XRD, SEM, TEM...

Titanium dioxide (TiO2) was doped with the combination of several metal ions including platinum (Pt), chromium (Cr), vanadium (V), and nickel (Ni). The doped TiO2 materials were synthesized by standard sol-gel methods with doping levels of 0.1 to 0.5 at.%. The resulting materials were characterized by x-ray diffraction (XRD), BET surface-area measurement, scanning electron microscopy (SEM), and...

The nanoparticles of gold doped with various percentage of copper (Cu 10%, 25%, 75%) were synthesized by wet-chemical method at room temperature. Copper (II) sulfate and gold (III) chloride trihydride was taken as the metal precursor and ascorbic acid as a reducing agent and anhydride maleic as surfactant. The reaction is performed with high-speed stirring at room temperature under nitrogen atm...

Abstract Heterogeneous composites of metalloporphyrins with TiO 2 possess exceptional photosensitizing properties, which works efficiently in degradation organic pollutants. Herein, vanadium porphyrin complex {VO(TPP)} was loaded on photocatalyst {VO(TPP)–TiO } by the wet impregnation method. The as-prepared catalysts were characterized to analyze physicochemical properties and photocatalytic 4...

Iron- and/or titanium-containing microporous silicoaluminophosphate catalysts have been synthesized, under hydrothermal conditions, using triethylamine structure directing, to obtain the aluminophosphate five phase (AFI). These solids were characterized by X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR), scanning electron microscopy (SEM), nitrogen adsorption measureme...

Pure TiO2 and Cu–doped containing different amounts of copper ions with anatase/rutile/brookite triphasic structure were successfully synthesized through a simple hydrothermal method. The obtained samples characterized by X–ray diffraction (XRD), Raman spectroscopy, scanning electron microscope (SEM), transmission (TEM), photoelectron spectroscopy (XPS), UV?vis diffuse reflectance (UV-DRS), pho...

The dual-functional Ca12Al14O33: Tb3+ and Ca12Al14O33: Sm3+ materials were prepared by the Self-Propagating Combustion Synthesis (SPCS) technology. The structure, morphology and light absorption property were investigated by XRD, FT-IR, UV-Vis DRS and SEM etc. The doping of Tb3+ and Sm3+ ions had not changed cubic structure of Ca12Al14O33 but leaded to the slight lattice dilatation and the red-...
