Photocatalytic Activity of Green Synthesis ZnO AND FeO Nanoparticles of Calotropis Gigantea Flower Extract

Green Synthesis of Zno and Feo nanoparticles is carried out by Calotropis gigantea flower extract with Zinc Acetate and Ferric Chloride salt. When the aqueous flower extract was put into the FeO Solution it turns into puple to brown colour immediately this indicates the reduction of iron ions in the solution and when the flower extract was put into the ZnO solution it turns into purple to dark green colour immediately this indicates the reduction of zinc ions in the solution. The synthesized FeO and ZnO NPs were characterized by UV, ITIR, XRD, DLS and SEM. It was utilized to determine the crystallinity, shape, and functional group responsible for the capping, reducing, and photocatalytic destruction of synthesized ZnO and FeO NPs. The degradation of Methyl Red and Crystal Violet dye under sunlight, which was used to examine the photocatalysis of synthetic ZnO and FeO NPs.
