Ti₁-x-yFexCoyO₂ nanosheets are synthesized in which the (Fe/Co) content is systematically controlled in the range of 0 ≤ x ≤ 0.4 and 0 ≤ y ≤ 0.2. A key feature of this new preparation is the use of (Li/Fe)-, (Fe/Co)- and (Li/Co)-co-substituted layered titanates as starting materials. In exfoliated nanosheets, the composition can be intentionally modified by controlled Fe/Co substitution into Ti...

Schiff base containing symmetric bis-dithiocarbamate ligand Na2[dtc-SB-dtc] (SB = Bi-Schiff base Phenylene diamine) is synthesized and metallated with Co(II)Cl2.6H2O to form [Co(dtc-SB-dtc).2H2O]n Co(dtc-SB) infinite coordination polymer (ICP) nanowires [Co(dtc-SB) NWs]. Pair of Satellites in X-ray photoelectron spectroscopy (XPS) spectrum of Co 2p confirm the formation of hexa-coordinated Co(I...

Titania, single-doped and lanthanum-silver co-doped titania nanocomposite were coated on cellulosic and polyacrylonitrile fibers via sol–gel method. The prepared samples were evaluated using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photolumines...

In this work we report synthesis and magnetic characterization of cobalt doped ZnO nanoparticles (with different percent of doped cobalt oxide). Synthesis of the materials was carried out at room temperature by polyacrylamide-gel method, using zink sulfate and cobalt nitrate as source materials, acrylamide as monomer and N,N-methylene bisacrylamide as a lattice reagent. Characterization of the ...

in the present study, the effects of calcium doping on the performance of the co-precipitated cu-mgo catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. the results proved that the addition of this promoter had a remarkable impact on the catalytic performance. the conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...

Structural and magnetic properties of a series of low doped Zn 1−x Co x O thin films deposited from Zn and Co metal targets on (0001) Al 2 O 3 substrates. Abstract We report on the synthesis of low doping Zn 1−x Co x O (0 < x < 0.1) thin films on (0001)-Al 2 O 3 substrates. The films were prepared in an oxidizing atmosphere, using the pulsed laser deposition technique starting from Zn and Co me...

lu3+/yb3+ and lu3+/er3+ co-doped sb2se3 nanomaterials were synthesized by a co-reduction method in hydrothermal condition. powder xrd patterns indicate that the lnxln′xsb2-2xse3 ln: lu3+/yb3+ and lu3+/er3+ crystals (x= 0.00-0.04) are isostructural with sb2se3. the cell parameters were increased for compounds upon increasing the dopant content (x). sem and tem images show that co-doping of lu3+/...
