Abstract Herein, we have synthesised cobalt (Co) and copper (Cu) co‐doped Ni‐ferrite Ni 1‐x Co x Fe 2‐y Cu y O 4 nanocrystals (NCs) via the facile micro‐emulsion method. The materials were analysed for various physio‐chemical characterizations to investigate co‐doping (Co Cu) effects on magnetic, structural, electrical, photo‐catalytic properties. structural analysis Fourier Transform Infrared spectroscopy (FTIR) X‐rays diffraction (XRD) showed successful fabrication of with cubic spinel geometry having a single phase, crystallite size was observed in 15 24 nm range. electrical response measured using current‐voltage (I–V) good features, resistivity declined from 6.85×10 7 Ohm.cm un‐doped 0.04×10 materials, which accredited due synergistic metal cations Ni‐based ferrite structures.

Using Phosphogypsum as a Source of Calcium Sulfate When Synthesizing Calcium Molybdate Nanoparticles

Reactions, Journal Year: 2024, Volume and Issue: 5(3), P. 462 - 471

Published: Aug. 7, 2024

Calcium molybdate (CaMoO4) is of significant interest due to its unique properties and numerous industrial applications, such as catalysis, electrochemistry, optoelectronics. In this study, we developed an economical environmentally friendly method synthesize calcium from Moroccan phosphogypsum (PG) waste sodium molybdate, all at room temperature. Comprehensive analysis through X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Raman vibrational spectroscopy, scanning electron microscopy (SEM) revealed the high purity synthesized with particle sizes only 12 nm. Additionally, optical characteristics were studied using ultraviolet-visible (UV-vis), which showed band gap Egap = 3.96 eV for CaMoO4. These results confirm successful synthesis nanoparticles phosphogypsum, demonstrating effective pathway valorize into a valuable material. This approach contributes environmental sustainability by reducing dependence on rare chemicals while offering innovative solutions industry’s sustainable development.
