摘要

This study reports the rapid and solvent-free synthesis of nickel oxide (NiO) nanoparticles using an atmospheric-pressure plasma jet method. This approach provides a green alternative to conventional chemical routes. X-ray diffraction (XRD) analysis confirmed the formation of high-purity cubic NiO nanoparticles with an average crystallite size of 17.87 nm. Energy-dispersive X-ray (EDX) spectroscopy verified the elemental composition. Morphological characterization using atomic force microscopy (AFM) and field-emission scanning electron microscopy (FESEM) revealed spherical and well-dispersed particles with average diameters of 96.24 nm (grain size) and 91.7 nm (particle size), respectively. UV-Vis spectroscopy yielded an optical band gap of 3.70 eV, indicating suitability for UV-active applications. The combination of high purity, appropriate band gap, and favorable morphology suggests these nanoparticles are promising for use in optoelectronics, catalysis, and biomedical applications.
