Synthesis of Metal Nanoparticles by Using Polyoxometalates as Photocatalysts and Stabilizers We thank the Ministry of Development, General Secretariat of Research and Technology of Greece, for supporting part of this work. We also thank Dr. A. Travlos for help with the TEM images.

Abstract

Fine metal nanoparticles of Ag, Au, Pd, and Pt were obtained at room temperature, by simple mixing of the corresponding metal ions with reduced polyoxometalates (POMs) that serve both as photocatalysts and stabilizers, according to the cycle shown.
