Abstract

Green synthesis of Ag 2 O nanoparticle (Ag 2 O NP) has been investigated using Vernonia amygdalina Del. leaf extract (VaDLE). The secondary metabolite of VaDLE plays a role as a base source and capping agents, which can be determined by phytochemical screening. The diffraction pattern and crystallinity of Ag 2 O NP was confirmed by X-ray diffraction, while the distribution size of Ag 2 O NP can be determined by using transmission electron microscopy. Fourier transform-infra red spectrum was used to show the interaction VaDLE and Ag 2 O NP. FT-IR characterization showed the presence of Ag-O band at 825 cm -1 . The characterization of UV-Vis spectrophotometer showed the typical absorption of Ag 2 O at maximum wavelength, λ max of 262 and 452 nm. The size distribution of Ag 2 O was 22.70 nm confirmed by particle size analyser. UV-Vis DRS characterization proved the bandgap energy of Ag 2 O at 1.56 eV. The photocatalytic activity of Ag 2 O NP was observed on the degradation of methylene blue. The result of the degradation percentage was 71.59%.
