Successive Photocatalytic Degradation of Methylene Blue by ZnO, CuO and ZnO/CuO Synthesized from Coriandrum sativum Plant Extract via Green Synthesis Technique

In this study, successful synthesis of ZnO nanoparticles (NPs), CuO NPs, and ZnO/CuO nanocomposite through an eco-friendly method using Corriandrum sativum leaf extract as a capping agent is reported. Using XRD, FTIR, UV-Vis, SEM techniques, the synthesized materials were characterized for structural analysis, functional groups identification, spectroscopic measurements, morphological analysis. The percentage composition purity samples determined by Energy Dispersive X-ray (EDX), which showed materials. Morphological analysis was done Scanning Electron Microscopy (SEM) reflected that NPs spherical, average size calculated Image J software around 25 nm, 55 11 respectively. FTIR UV-Vis analyses used synthetic confirmation characteristic peaks (ZnO, CuO, CuO/ZnO) nanomaterials evaluated photocatalytic activity methylene blue (MB) dye. Among all three photocatalysts, composite maximum photodegradation compared to other two present work could lead pathway decontamination harmful dyes wastewater released from different industries.
