Activity revived : Platinum nanoparticles (cuboctahedra, cubes, and porous particles, see picture, from left to right) capped with alkylammonium ions are synthesized by manipulating the reduction kinetics. The catalytic activity of these nanoparticles is superior to that of nanoparticles whose shape was controlled with a polymeric capping agent and foreign metal ions.
