Synthesis and characterization of NiFe2O4/CuO nanocomposites: Structural and magnetic properties analysis
Copper oxide nanoparticles (CuONPs) were synthesized through the precipitation method, while nickel ferrite nanoparticles (NiFe2O4NPs) were prepared using the co-precipitation method involving mixtures of NiCl2 and FeCl3. Additionally, nanocomposites of (NiFe2O4/CuO) with crystalline phases were obtained using the ceramic method. Various characterization techniques including XRD, EDS, SEM, FE-SEM, and VSM were employed to analyze and examine the properties of the powders. XRD was utilized to assess the purity of the phases, investigate the structural formation, and determine the sizes of the crystallites for all the particles. The XRD analysis provided insights into the crystal structures of the materials under investigation. It revealed that CuO exhibited a monoclinic structure, while nickel ferrite and the nanocomposites displayed a cubic spinel structure. A (NiFe2O4/CuO) nanocomposite was created using ceramic techniques and sintered at 600 °C. FE-SEM analysis showed round particles and clear grain boundaries. The preparation process involved various factors influencing particle growth rate and final microstructure. EDS pattern confirmed absence of impurities; surface layers displayed significant Ni, Fe, Cu, and O components. Magnetic measurements using VSM confirmed the ferromagnetic nature of both NiFe2O4 and NiFe2O4/CuO. The study further investigated the impact of CuO nanoparticles and their concentration on the structure and magnetic properties of the resulting nanocomposites.
期刊介绍：
Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
