In order to deepen the understanding of role transition metal oxides in electron transfer at electrochemical interface, performance Zn x Ni 1− Fe 2 O 4 ( = 0, 0.2, 0.4, 0.6, 0.8, 1) nanomaterials sensing is studied. Nanomaterials are synthesized by simple autocombustion synthesis procedure. Field‐emission scanning microscopy characterization shows that particles have a size between 30 and 70 nm...

The innovation and development of water purification methods have been at the center extensive research for several decades. Many nanoparticles are frequently seen in industrial waste water. In this research, zinc oxide (ZnO) were synthesized following an autocombustion method with without honey capping. Structural crystallinity bonding structure examined via X-ray diffraction (XRD) analysis Fo...

In this research, a sol gel autocaombustion route has been proposed to synthesize alumina-zirconia composite powders, using ammonium bicarbonate as a new fuel. Then the effect of calcination temperature on phase transformation and crystallite sizes was investigated. To characterize the products XRD, TEM and BET analyses were used. XRD patterns of as-synthesized powder and calcined powders at 11...

The main difficulty in the liquid phase furfural hydrogenation process is control of selectivity to target product among possible ones. When copper catalysts are used, they often suffer from low stability medium. Herein, we report a general preparation method based on glycine-assisted situ autocombustion synthesize Cu supported catalysts. This could lead highly active, selective and stable hydr...

Iron oxide (Fe2O3) nanoparticles were prepared by combination of sol-gel autocombustion and ultrasonic irradiation. The XRD pattern reveals that the crystallite size of sample is 36.7 nm and the phase identification shows hematite, syn has been crystalized. The morphology of the sample investigated by FESEM showed that particle size of the sample was about 76 nm. The optic...

The La0.67Ca0.2Ba0.13Fe1?xMnxO3 perovskite compounds with different manganese concentrations (x = 0.0, 0.03, 0.06) were synthesized by the autocombustion method and annealed at 700 °C. X-ray diffraction (XRD) data indicated that all obtained crystallize in cubic structure Pm $$\overline{3}$$ m space group. increase substitution rate has been found to lead decrease crystallite size value charact...

Hammada scoparia (Pomel) is a powerful plant with important biological properties. In this study, we report on the green synthesis of silver-doped nickel and copper nanoparticles (NPs) in presence H. leaf extract using self-propagating sol–gel autocombustion process. The synthesized NiO, CuO, Ag-NiO, Ag-CuO NPs were characterized Fourier transform infrared spectroscopy (FTIR) X-ray diffraction ...
