Stable gold nanoparticles (AuNPs) were synthesised from aqueous 1 M chloroauric acid and Moringa oleifera flower aqueous extract. The UV-vis spectrum of AuNPs displays the surface plasmon resonance at 540 nm. The AuNPs were characterized using transmission electron microscopy, scanning electron microscopy, energy dispersive X-ray analysis and dynamic light scattering whilst Fourier transform infrared and H-1-NMR spectroscopy were used to probe the type of capping agents. The AuNPs were assessed for their catalytic reduction of nitrophenol and nitroaniline by UV-vis and showed a rapid reduction within 3 min thereby indicating degradation of industrial effluents. Furthermore, the AuNPs may possess good anti-cancer properties. (C) 2014 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V. All rights reserved.
