this paper reports the synthesis and characterization of photocatalyst cds nanoparticles for investigation of photocatalytic degradation of 2,4,6-trichlorophenol. cds nanoparticles were synthesized by the microwave-assisted sol-gel method and characterized by various techniques such as x-ray diffraction, filed emission scanning electron microscopy, energy dispersive spectroscopy, fourier transf...

nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. in this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of prangos ferulaceae leaves. the synthesized silver nanoparticles were characterized by uv-vis spectroscopy, scanning el...

molecular sieves mcm-41 were synthesized from rice husk ash (rha) as alternative sources of silica. the material was synthesized by a room temperature method from a gel with the molar composition sio2: 1.6ea: 0.215hdtmabr: 325h2o with ph correction. the cetyltrimethylammonium bromide (ctmabr) was used as a structure template. nanocomposite containing 5.0 and 10.0 wt.% of cu was synthesized unde...

new two nano- sized schiff base complexes [m(l)], where l= 2, 2'-((1e, 1e')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and m=cu or zn, (a, b complexes) were synthesized by ultrasonic irradiation. these complexes were characterized by elemental analysis, molar conductivity, ft-ir, fluorescence emission, 1h nmr, field emission scanning electron sp...

The geometric and electronic structures of cold host-guest complex ions of crown ethers (CEs) in the gas phase have been investigated by ultraviolet (UV) fragmentation spectroscopy. As host CEs, we chose 15-crown-5 (15C5), 18-crown-6 (18C6), 24-crown-8 (24C8), and dibenzo-24-crown-8 (DB24C8), and as guests protonated-aniline (aniline·H(+)) and protonated-dibenzylamine (dBAM·H(+)) were chosen. T...

On the basis of in situ MAS NMR technique under flow conditions,1-4 the combined in situ MAS NMR-UV/Vis spectroscopy5 has recently been developed to obtain complimentary information on solid catalysts and, therefore, to better elucidate the mechanism involved in heterogeneous catalysis. While NMR spectroscopy allows the identification of species on the working catalyst in more detail, UV/Vis sp...

UNLABELLED Pure zinc oxide and zinc oxide/barium carbonate nanoparticles (ZnO-NPs and ZB-NPs) were synthesized by the sol-gel method. The prepared powders were characterized by X-ray diffraction (XRD), ultraviolet-visible (UV-Vis), Auger spectroscopy, and transmission electron microscopy (TEM). The XRD result showed that the ZnO and BaCO3 nanocrystals grow independently. The Auger spectroscopy ...
