New Cd(1−X)CoXO stoichiometric nanocomposite system: Synthesis, structure, magnetic and surface area properties

In this work a new nanocomposite system of Cd(1−X)CoXO (0.0 ≤ X ≤ 1.0 mol) is presented. The nanocomposite system has been synthesized using the hydrothermal method. The composition of the synthesized system is confirmed with the EDX technique. The synthesis, structure, magnetic, and surface area properties of the synthesized Cd(1−X)CoXO nanocomposite system are reported. The structure has been studied with X-ray diffraction, TEM, and SEM, which confirms the formation of the nanocomposite. The new nanocomposite system of Cd(1−X)CoXO possess fcc CdO, fcc CdCoO, and fcc Co3O4 phases. Celref Unit-Cell refinement code was used to determine the lattice parameter (a, b and c), bond length (l), cell volume (V) and theoretical density (ρ), while the average crystallite size (Dav), dislocation density (ε), and the microstrain (δ) was calculated using the Scherrer equation. The M − O (metal-oxide) bonds were investigated with the FTIR technique. In addition, we analyze the magnetization curves and the mass magnetic susceptibility (χmass) of the system. The surface area has been determined and discussed using Brunauer–Emmett–Teller method (BET). Lastly, the effect of Co2+ ions concentration on the above studies is discussed. •A new nanocomposite system Cd(1-X)CoXO was prepared.•Crystallization phases were obtained as fcc CdO, fcc CdCoO, and fcc Co3O4.•Particle size from surface area and XRD are consistent.•Metal-oxygen bond length was determined from FTIR spectra.•This system exhibits paramagnetic properties.
