In this research, the effects of transition metal (Ni) doping to metal-oxide nanoparticles (TiO2) were studied. Various weight ratios (5, 10, 15, and 20%) Ni-to-TiO2 synthesized using sol–gel technique. These doped prepared titanium butoxide nickel nitrate as precursors methanol a solvent. The Ni TiO2 examined variety characterization techniques, X-ray diffraction (XRD), Fourier-transform-infrared (FTIR) spectroscopy, ultraviolet–visible (UV–Vis) field-emission scanning electron microscopy (FESEM), vibrating sample magnetometer (VSM). XRD reveals that Ni-doped crystallizes in tetragonal structure with anatase phase. particle size lattice strain calculated by Williamson–Hall equation. presence strong chemical bonding functional groups at interface was confirmed FTIR. optical properties undoped samples recorded UV–Vis spectroscopy. saturation magnetization (Ms) found higher for compared samples. surface morphology element FESEM.
