Room temperature synthesis of platinum nanoparticles in water-in-oil microemulsion

Platinum nanoparticles of less than 5 nm size have been synthesized by the reduction of H2PtCl6 using sodium borohydride in water-in-oil (w/o) microemulsions of water/TritonX-100/cyclohexene/1-hexanol at 25 +/- 2 degrees C. Size and shape of the particles are determined through HRTEM images. (C) 2008 Elsevier B.V. All rights reserved.
