Synthesis of Nano-Aluminum Oxide via Biological and Electrochemical Methods

Abstract

In this research work, the nanoparticles of aluminum oxide were synthesized by two ways. The first way is the biological by using (Pseudomonas aeruginosa) bacteria with a rate diameter (102.35) nm. The second way is the electrochemical with a rate diameter (62) nm. These nanoparticles were characterized by Atomic Force Microscopy (AFM), X-Ray diffraction technique (XRD), Transmission Electron Microscopy (TEM) and Scanninig Electron Microscopy (SEM). Alumina nanoparticles are thermodynamically stable particles over a wide temperature range . The biological activity of these nanoparticles toward different species of pathogenic bacteria (Staphylococcus aureus ) and (Pseudo monas) has been investigated. The results stated that the nanoparticles prepared by chemical way was more effective on the inhibition of bacteria than the nanoparticles prepared by biological way

Synthesis of Nanostructured Alumina from Byproduct Aluminum Filings: Production and Characterization

“…The production and characterization of this invaluable inorganic substance have been examined by many researchers [11,[23][24][25]. Production of alumina in the nanoscale range starting from aluminum waste was reported by Barakat et al [26] and Nduni et al [27]. In addition, an active combustion catalyst can be manufactured with approximately 75% of its composition relying on Al foil waste [28].…”
