Orientations of polyoxometalate anions on gold nanoparticles Academic Article uri icon


  • Cryogenic transmission electron microscopy of polyoxometalate-protected gold nanoparticles reveals that the Preyssler ion,[NaP5W30O110] 14–, lies “face down” with its C5 axis perpendicular to the gold surface, while the Finke–Droege ion,[P4W30Zn4 (H2O) 2O112] 16–, is “tilted”, with its long axis close to 60° from the normal to the surface.
