摘要：

Eucalyptus globulus leaf extract mediated synthesis of spherical zinc oxide nanoparticles (ZnO NPs) was carried out under ambient conditions. UV-Visible studies of the synthesized nanoparticles revealed the characteristic peak at 361 nm indicating the formation of ZnO nanoparticles. Powder X-ray Diffractometric (XRD) study showed the strong, intense and narrow-width diffraction peaks indicating the formation of crystalline nanoparticles with most stable hexagonal phase. Field emission-scanning electron microscopy (FE-SEM) and high resolution-transmission electron microscopic (HR-TEM) results confirmed the formation of spherical ZnO NPs with mean particle size of 11.6 nm which is in close agreement with XRD pattern. Further, energy dispersive X-ray diffraction analysis (EDAX) revealed the formation of highly pure ZnO NPs with the peaks of Zn and O atoms. ZnO NPs exhibited effective photocatalytic activity in degrading Methylene blue and Methyl orange with maximum degradation efficiency up to 98.3% at 30 mg of catalyst doses. In addition, ZnO NPs exhibited high antioxidant activity against DPPH free radicals scavenger. (c) 2016 The Society of Powder Technology Japan.
