Green Synthesis of CuO@Hydrochar by lavandulifolias Extract andEvaluation of Extract effects on the Nanoparticles Morphology and Size

The use of plant extracts in the synthesis of nanoparticles can be an eco-friendly[۱], costeffectiveand easy-to-synthesize method as well as an alternative to conventional methods suchas physical and chemical ones; this has made the green synthesis of nanoparticles of interest tomany researchers[۲,۳]. As part of this work, CuO nanoparticles and nanocomposites withhydrogen storage capability were synthesized. The extract of Stachys lavandulifolia is used asthe reducing agent for Cu+۲ in the biosynthesis of CuO NPs in the presence of ۱ Mm CuCl۲solution, then the nanocomposite was synthesized based on hydrochar. The physical andchemical properties of the CuO nanoparticles and nanocomposite have been analyzed in thefacility of X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transforminfrared (FT-IR). X-ray diffraction (XRD) patterns have been investigated for the detection ofphase and size and crystal structure as well as the proof of the formation of CuO nanoparticlesand nanocomposite, scanning electron microscopy (SEM) for morphology and FourierTransform Infrared (FT-IR) analysis is for difference bonds checked.
