In this paper, MgAl2O4 nanoparticles were synthesized by the Sol-gel auto combustion method and were doped with different concentrations of Ni2+ (x= 0, 0.1, 0.05, and 0.03). By this method, a novel photocatalyst which had better decolorization percentages of Congo redcompared to MgAl2O4 was produced. The MgAl2O4 sample...

Metal oxide photocatalyst is a promising wastewater treatment process due to its simplicity, high efficiency, and low cost, as well being environmentally friendly non-energy consuming. The perovskite structure material, SrTi1?xNbxO3 (STNO) with x = 0, 0.01, 0.03, 0.05, was successfully synthesized by the sol-gel auto-combustion method. Samples pure phase cubic were obtained. Rietveld refinement...

the mössbauer spectra of nanoferrite materials such as ni0.25mn0.75fe2o4, co0.5mn0.5fe2o4 and ni0.4co0.6fe2o4 have been reported and the above materials were prepared by sol-gel combustion method using metal nitrates as source material and polyvinyl alcohol(pva) as agglomeration reducing agent. as the structural, thermal and magnetic properties (vsm) of the above ferrites have been published al...

Ni and La substituted M-type Ca hexaferrite of composition CaNi1Fe11O19 CaLa1Fe11O19 were synthesized by sol-gel auto combustion method using metal nitrates as oxidants citric acid reducing agent. The prepared samples characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), energy dispersive analysis (EDAX), vibrating sample magn...

In this study, a series of nanocrystalline Ni0.7Cu0.30AlxFe2-xO4 (x = 0.00 to 0.10 with step 0.02) has been synthesized through the sol–gel auto combustion technique. The structural, morphological, dielectric, and electrical properties nanoparticles are analyzed due substitution effect Al3+ content. structural study performed XRD FTIR analyses. extracted patterns assure single-phase cubic spine...
