【 摘 要 】

Nickel Oxide nanoparticles (NiO-NP) have been successfully synthesized using Ageratum conyzoides L. leaf extract via green method. The optical, structural, and morphology of NiO-NP were characterized. The characterization UV-Vis spectrophotometer showed a typical peak of NiO-NP at maximum wavelength of 324 nm. FT-IR characterization confirms that the stretching vibration of Ni-O occurs at wavenumber of 434 cm-1. The particle size distribution of NiO-NP was 50.70 - 91.3 nm characterized by PSA. The XRD pattern showed the crystallinity of NiO-NP with cubic structure. TEM image showed the particle size of NiO-NP was 8-15 nm. The catalytic activity percentage of NiO-NP shown 83% in the reduction of methylene blue compared to catalytic activity without catalyst was 28% for 18 minutes.
