【 摘 要 】

The synthesis of metal nanoparticles through a green method is a rapid biogenic and offers few advantages over the common chemical and physical procedures, as it is an easy and fast, eco-friendly and does not involve any costly chemicals as well as hazardous chemicals. In this study, we report synthesis of CuO NPs by using Drypetes sepiaria Leaf extract (DSLE). The synthesized CuO NPs was characterization using different technique such as UV, IR, XRD, and TEM. The formation of CuO NPs was confirmed by Surface Plasmon Resonance (SRP) at 298 nm using UV-Vis spectroscopy. Crystallinity of CuO NPs was confirmed by powder XRD and the characteristic functional groups of synthesised CuO NPs were identified by FTIR spectroscopy. The size and shape of the synthesized CuO NPs was determined by transmission electron microscopy (TEM). In addition, we performed photocatalytic activity to examine the photocatalytic degradation efficiency of CuO NPs to Congo Red. The colloidal solutions of CuO NPs showed good catalytic activity.
