Sonoelectrochemical Synthesis of Metallic Aluminum Nanoparticles

In this paper, we report for the first time on the room‐temperature preparation of metallic aluminum nanoparticles by the pulsed sonoelectrochemical method. The prepared nanoparticles were characterized by X‐ray diffraction (XRD), high‐resolution scanning electron microscopy, transmission electron microscopy (TEM), and high‐resolution transmission electron microscopy. TEM analysis shows that the prepared aluminum nanoparticles range from 10 to 20 nm in size. The XRD pattern confirms the formation of metallic aluminum nanoparticles. The results show that the sonoelectrochemical technique is a promising method for the fabrication of air‐sensitive metallic nanoparticles that have a high, negative reduction potential.(© Wiley‐VCH Verlag GmbH & Co.
