ZnMnO3/Fe3O4 magnetic nanocomposites were fabricated via facile co-precipitation route and were calcined at 400 °C for 3 h. Synthesis of ZnMnO3/Fe3O4 magnetic nanocomposites were optimized by different weight percentages. Then, the as-synthesized sample was characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), photoluminescence(PL), vibrating Sample Magnetometer (VSM), EDAX (Energy dispersive X-ray analysis), diffuse reflectance UV–Vis spectroscopy […]
The anatase TiO2-supported Ni–Cu bimetallic catalyst was prepared by Co-impregnation method and after shaping by three binders (bentonite, polyethylene glycol and poly vinyl alcohol) into extrudes, the effect of calcining temperature (200 °C, 400 °C, 600 °C and 800 °C) and calcining time (1, 3, 5 and 7 h) on the extrudes were investigated. According to the obtained results, the […]
This work deals with the preparation of polyacetal (PAC)/graphene nano-platelets (GNP) and/or polypyrrole (PPY) in the presence of cobalt acetate-based composites. These materials were simply prepared via in situ emulsion in combination with sonication strategy technique. The resulting composites were characterized via Fourier transform infrared spectroscopy, thermogravimetric analysis, transmitting electron microscope, and particle size distribution […]
A terpolymer resin derived from Resorcinol, Formaldehyde and Salicylic acid was synthesized through condensation reaction. Transition metal ions namely Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) were incorporated into the resin forming polymer-metal complexes. Both the resin and the complexes were characterized by FTIR, UV–Vis., XRD, 1H NMR, TGA and SEM/EDX. Elemental analysis was carried out […]
Hexadecylamine-capped PbS nanoparticles were prepared from lead(II) complexes of dibenzyl dithiocarbamate (Dibzydtc) [PbS 1], imidazolyl dithiocarbamate (Imdtc) [PbS 2], 2-oxo-pyrrolidine dithiocarbamate (Pydtc) [PbS 3], diallyl dithiocarbamate (Diallyldtc) [PbS 4], and dihexyl dithiocarbamate (Dihexdtc) [PbS 5], at 120 °C. Powder X-ray diffraction patterns of the PbS nanoparticles are indexed to the face-centered cubic phase. The average particle […]
Novel blue pigments were prepared from copper, magnesium, aluminum nitrate solutions and phosphoric acid with pH adjustments (pH 5, 7, 9). The obtained precipitates were heated at 300, 500, and 700 °C for 1 h. The precipitates and their thermal products were estimated with X-ray diffraction (XRD), infrared (IR) spectra, ultraviolet–visible (UV–Vis) reflectance spectra, and L*a*b* color […]
Low-carbon steel (LCS) in 0.5 M sulphuric acid is used to check the corrosion resistance performance of Pfaffia paniculata (P. paniculata) root extract. Notably, P. paniculata showed 91% corrosion resistance efficiency at 600 mg/L concentration. The adsorption of this inhibitor follows the Langmuir adsorption isotherm suggesting its monolayer formation on the LCS surface. The potentiodynamic polarization experiments […]
Magnesium ferrite is a visible light absorber, and when combined with multiwall carbon nanotubes (MWCNTs), it can lead to low electron–hole recombination rates, thus improving its photocatalytic activity. In this work, a novel MgFe2O4/CNTs nanocomposite catalyst has been synthesized via anchoring MgFe2O4 nanoparticles onto MWCNTs surface by a sol–gel and microwave-assisted route. The prepared catalyst […]
