Nanoparticles of copper (Cu). nickel (Ni). and silver (Ag) were synthesized in supercritical methanol or supercritical ethanol at 300 bar, 400 degrees C and reaction time of 5 min. The supercritical alcohol acted both as reaction medium and as a reducing agent. The synthesized particles were spherical in shape. The average diameter of Cu, Ni, and Ag particles was 420 +/- 119 nm, 50 +/- 10 nm, and 390 +/- 114 nm, respectively. Crown Copyright (C) 2009 Published by Elsevier B.V. All rights reserved.
