Effect of variation biomass on the properties of iron oxide NPs for hydrolysis of methylene blue dye

Abstract Three plants extracts of Eucalyptus, Pomegranate and Oolong tea leaves have been used to synthesize iron oxide nanoparticles. The structure particle size the nanoparticles investigated by XRD spectrum. results exhibit polycrystalline nature material with a around (17-19 nm). FESEM analysis showed that using different as reduction capping agent might affect shape such forming round, polygon irregular shapes under same conditions. photo catalyst activity prepared NPs in degradation MB dye has investigated. good efficiency reached 91%, 88% 80%.
