Abstract :

Nickel oxide (NiO) nanoparticles were successfully synthesized using the co-precipitation method. The resulting products were subjected to calcinated at 400°C and subsequently analyzed using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and UV–vis absorption spectroscopy. The obtained findings confirm the presence of nickel oxide nano powders created during co-precipitation. The XRD patterns revealed the synthesis of cubic crystal structure NiO NPs, with a preferred orientation of (200). The FT-IR spectra exhibited a distinct absorption peak at approximately 550 cm−1, indicating the presence of the Ni-O bond in the NiO NPs. Additionally, the UV-vis absorption spectra indicated that the NiO NPs had an absorption edge wavelength of 245 nm and an energy band gap of 4.5 eV.
