Pt nanoparticles (NPs) of different shape (cubic and octahedral/tetrahedral) and size (5–10 nm) were synthesized by one-step polyol-based synthetic procedures that permit the concomitant control of the shape and size. The shape and size stability of these particles under repetitive methanol (MeOH) e...
