Green Synthesis And Characterization Of Copper Oxide Nanoparticles Using A Red Seaweed Gracilaria Edulis
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 10
Abstract
This work represents a novel and eco-friendly method for synthesizing copper oxide nanoparticles from a red seaweed- Gracilaria edulis. The method used for synthesizing nanoparticles was sol-gel method. Seaweed was collected from Rameshwaram, with the help of local fishermen and identified using keys available. Morphological criteria of Seaweeds were confirmed at the Regional Center of CMFRI, Mandapam Camp, Tamil Nadu.. The synthesized nanoparticles were characterized using UV spectroscopy showed a surface plasmon peak at 410 nm, which is characteristic peak of Copper oxide nanoparticles.Using energy dispersive X-ray spectrometry (EDX) analysis, a distinct peak of CuO was confirmed. Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and UV-visible absorption spectroscopy confirmed the reduction of Copper oxide nanoparticles. The complete reduction of metal ion was attained within 5 hours of time span. This is the first study on synthesis of copper nanoparticles using a red seaweed.
