Eco-friendly synthesis of aluminium oxide nanoparticles was achieved by a novel, facile green route method using aerva lanta and terminalia chebula as a reducing agent. Aluminium oxide nanoparticles (Al 2 O 3 ) were synthesized from aluminium nitrate using extracts of aerva lanta leaves and terminalia chebula seeds. Nanoparticles produced by plants are more stable and rate of synthesis is faster than that in other organisms. The present investigation was carried out to green synthesis of alumina nanoparticles by using medicinal plants. Deionised Water was taken as solvent medium. The formations of AlNP were initially monitored by the colour changes occurring in the reaction mixture during the incubation period. The successful formation of alumina nanoparticles has been confirmed by X-ray diffraction, UV-visible, FTIR and FE-SEM analysis. The X-ray diffraction data revealed the average size of the Al-NPs as 70 nm. The AlNP were found to be spherical agglomeration in shape in case of aerva lanta leaves extract with a size of 50-70 nm and to be spherical shaped in case of terminalia chebula seed extract with an average size of 50-100 nm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
