Synthesis of Metallic Nanoparticles Using Electrogenerated Reduced Forms of [α-SiW12O40]4- as Both Reductants and Stabilizing Agents. — Reduced forms of [α-SiW12O40]

4- are produced by controlled potential bulk electrolysis with little or no supporting electrolyte. Without the need for separation and purification, these reduced forms are directly used as both the reductants and the stabilizing agents for the size-con-trolled synthesis of various types of metallic and alloy nanoparticles, including Au, Ag, Pt, Pd, Ni, and Ag—Au. The obtained Pt nanoparticles display attractive electrocata-lytic properties in methanol oxidation. — (ZHANG, J.; TING, B. P.; KOH, Y. T.; YING*, J. Y.; Chem.
