Biosynthesis of the CuO nanoparticles using Euphorbia Chamaesyce leaf extract and investigation of their catalytic activity for the reduction of 4-nitrophenol

Through this study an eco-friendly, simple, efficient, cheap and biocompatible approach to the biosynthesis and stabilisation of CuO nanoparticles (NPs) using the Euphorbia Chamaesyce leaf extract is presented. The CuO NPs were monitored and characterised by field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, Fourier transformed infrared spectroscopy, transmission electron microscope and UV-visible spectroscopy. The biosynthesised CuO NPs showed good catalytic activity for the reduction of 4-nitrophenol (4-NP) in water during 180s and reused 4 times without considerable loss of activity.
