Y2Ce2O7 nano powders were synthesized via sol-gel reactions at 900 (S1), 1000 (S2) and 1100 (S3) ˚C for 4 h using yttrium acetate (C6H9O6Y.xH2O), ammonium cerium nitrate ((NH4)2Ce(NO3)6) and stearic acid (C18H36O2) as raw materials at stoichiometric 1:1 Y:Ce molar ratio. The synthesized materials were characterized by powder X-ray diffraction (PXRD) technique and Fourier transforms […]
Mesoporous nanostructured γ-Al2O3 powders were synthesized through multi- step precipitation procedures using the pH-swing technique. Structural and morphological characteristics in addition to the thermal behavior of the procured samples were characterized via X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fourier transform infrared (FT-IR) spectroscopy, thermogravimetry-derivative thermal gravimetric (TG-DTG) and N2 adsorption–desorption isotherm. Plackett-Burman […]
In this research, first, nanoparticles of SrFe11.98Mg0.1Sn0.1O19 hexaferrite was synthesized via sol-gel auto-combustion process and then the nanocomposites of hexagonal ferrites/perovskite with the amounts of SrFe11.98Mg0.1Sn0.1O19/BaTiO3 (50/50, 40/60, 70/30 w/w) was prepared by the ball-milling method. Fourier transform infrared (FTIR) spectrums of SrFe11.98Mg0.1Sn0.1O19,was shown that the bands at about 400 and 500 cm-1 proved the […]
In this study, the reaction of 3-Picrylamino-1, 2, 4-Triazole (PATO) with B12N12 was investigated by density functional theory in the B3LYP/6-31G(d) level of theory. There were two possible isomers for reaction of PATO with B12N12 via carbon and nitrogen atoms of triazole ring to the Born atom of B12N12 (I and II-isomers). Thermodynamic parameters of […]
In this paper, a series of BaLaxGdxFe12-2xO19 (x=0.2, 0.4, 0.6 and 0.8)/PANI (polyaniline) nanocomposites synthesized for investigating the photocatalytic properties. Barium hexaferrite doped with La3+ and Gd3+ prepared via a sol-gel auto-combustion method and then the binary nanocomposites fabricated by the in situ polymerization method. (Fourier transform infrared) FTIR, (x-ray diffraction) XRD, (field emission electron […]
In the present investigation, ZnFe2O4@MnO and MnFe2O4@ZnO magnetic nanocomposites were fabricated via a facile hydrothermal method and were calcined at 300 °C for 3 h. Synthesis of ZnFe2O4@MnO and MnFe2O4@ZnO magnetic nanocomposites optimized by the different weight percentages. The synthesized photocatalyst was characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), Vibrating Sample Magnetometer (VSM), […]
