A facile chemical synthesis of CuxNi(1−x)Fe2O4 nanoparticles as a nonprecious ferrite material for electrocatalytic oxidation of acetaldehyde

A facile chemical synthesis of CuxNi(1−x)Fe2O4 nanoparticles as a nonprecious ferrite material for electrocatalytic oxidation of acetaldehyde
In the present work, Cu-doped nickel ferrite (CuxNi(1−x)Fe2O4) nanoparticles (CuNFNPs) were chemically fabricated by adding citric acid as a capping agent followed by combustion and calcination for acetaldehyde oxidation reaction (AOR) in KOH electrolytes. The as-prepared CuNFNPs were studied in terms of Fourier-transform infrared spectroscopy (FT-IR), Transmission electron microscopy (TEM), Field emission scanning electron microscope (FE-SEM), Energy-dispersive X-ray spectroscopy (EDX), ...

Doping of Nano Zinc Ferrites by Chromium: Structural and Magnetic Properties Studies
A SERIES OF CHROMIUM-SUBSTITUTED ZINC FERRITES (CRXZN FE2-XO4 WITH = 0.00, 0.10, 0.20, 0.30, 0.40) WERE SYNTHESIZED VIA HYDROTHERMAL METHOD. THE STRUCTURAL CHARACTERIZATIONS OF ALL THE PREPARED SAMPLES WERE DONE USING XRD, FTIR AND EDAX, TEM, HR-TEM AND TGA MEASUREMENTS . THESE STUDIES CONFIRMED THE FORMATION OF SINGLE-PHASE INVERSE SPINEL STRUCTURE IN ALL THE COMPOSITIONS. FROM HR-TEM MEASURMENTS, CRYSTALLINITY ARE ... Read more
