| Abstract: | Based on a polyol process, one-step synthetic procedures were investigated for concomitant control of the shape and size of
platinum nanoparticles (Pt NPs). Cubic and octahedral/tetrahedral particles of different sizes (5–10 nm) were synthesized
using these procedures. Further attempts to control the shape of the NPs below 3–4 nm failed. It was found that 3–4 nm is
the particle size limit for Pt NPs above which the particle size and shape can be concomitantly controlled. |
