Synthesis and Characterization of Aluminum Oxide Nanoparticles Using Macroalgae Sargassum Ilicifolium
MetadataShow full item record
Nanoparticle biosynthesis is considered an important part of nanotechnology which is economically viable; it is an environmentally-friendly procedure with great advantages compared to physical and chemical ones. In the present study, a green approach is presented for the first time for producing alpha aluminum oxide nanoparticles using Sargassum ilicifolium algae in which its methanolic algae extract was employed as a reducing agent and stabilizer layer. Under optimal conditions of 25ºC and pH=4, 10% of algae extract concentration and 0.05M Al2(SO4)3 salt, aluminum cations were reduced completely to nanoscale phase within 24 hours. XRD technique confirms the formation of alpha aluminum oxide size 35 nanometers in a hexagon shape. The results of TEM confirms the spherical almost shape of the produced nanoparticle, the results of SEM shows the average size 33.40 of the nanoparticle, and the results of EDX indicated the purity of the produced nanoparticle which is formed of onl.....
