Nanoparticle (NPs) have attracted the attention of scientists and researchers in water remediation due to the
improvement in its processability, and its cost effectiveness. The present work analyzed the synergistic effect of
CuO (NPs) with different ratios (0, 0.5, 0.6, 0.7, 0.8, 0.9 and 1 wt %) on the structural, and optical properties of
Fe3O4 (NPs), that can be used in water desalination process. The general methodology for preparation and
structural properties of CuO (NPs), Fe3O4 (NPs) and CuO/Fe3O4 (NCs) were analyzed by (XRD) and (TEM)
measurements. The morphological combination of (SEM) with (EDX), were used for determining the elemental
identification of CuO/Fe3O4 (NCs). The characterization topography was found to be strongly affected by the
change of the CuO concentration. Furthermore, the Urbach energy (EU), steepness parameter (σ), electronphonon
interaction (Ee-p), optical band gap (Eg), refractive index (n) and optical conductivity (σopt) were
calculated. The optical absorption studies in the UV–Visible region, revealed that the CuO/Fe3O4 (NCs) was
found to be direct allowed transition, and the energy bandgap value decreased from 2.52 eV to 2.15 eV based on
the percentage change of CuO (NPs) in CuO/Fe3O4 (NCs). Moreover, the value of thermal conductivity (k), and
thermal efficiency (η), showed an increase with the increase of the ratio of CuO (NPs), which may be an indication
for opening an innovation way that can satisfy the need of seawater desalination technology. |
