Green Synthesis of Aluminium Oxide Nanoparticles by using Aerva Lanta and Terminalia Chebula Extracts

Abstract

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.
