Generation of aluminum nanoparticles using the DC spark method in solution

In this investigation, a physical methodology of preparing aluminum nanoparticles suspended in the deionized water is presented. For this purpose, the DC spark method is applies and presented the size distribution and measurement by Transmission Electron Microscopy, TEM, of the nanoparticles in 25 V. The obtained results using the DC spark method show that the fabrication of aluminum nanoparticles in deionized water without any surfactants and stabilizers is relatively cheap and pollution free. Using the method, the aluminum nanoparticles could prepare smaller than 20 nm.
