Abstract EN
The effect of ethylenediaminetetraacetic acid (EDTA) as a capping agent on the structure, morphology, optical, and magnetic properties of nickel oxide (NiO) nanosized particles, synthesized by coprecipitation method, was investigated.
Nickel chloride hexahydrate and sodium hydroxide (NaOH) were used as precursors.
The resultant nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM).
XRD patterns showed that NiO have a face-centered cubic (FCC) structure.
The crystallite size, estimated by Scherrer formula, has been found in the range of 28–33 nm.
It is noticed that EDTA-capped NiO nanoparticles have a smaller size than pure nanoparticles.
Thus, the addition of 0.1 M capping agent EDTA can form a nucleation point for nanoparticles growth.
The optical and magnetic properties were investigated by Fourier transform infrared spectroscopy (FTIR) and UV-vis absorption spectroscopy (UV) as well as electron paramagnetic resonance (EPR) and magnetization measurements.
FTIR spectra indicated the presence of absorption bands in the range of 402–425 cm−1, which is a common feature of NiO.
EPR for NiO nanosized particles was measured at room temperature.
An EPR line with g factor ≈1.9–2 is detected for NiO nanoparticles, corresponding to Ni2+ ions.
The magnetic hysteresis of NiO nanoparticles showed that EDTA capping recovers the surface magnetization of the nanoparticles.
