Special project in chemistry presentation on "Synthesis of Shape-Controlled Metal Nanoparticles".

1. Synthesis of Shape-Controlled
Metal Nanoparticles
Roxana Y. Treviño

2. SEM Images of Octahedron Shaped
Nanoparticles:
• SEM Pd Nanoparticle Octahedron Shape- • SEM Au Nanoparticle (hypothesis/results)
Octahedron Shape (72hrs at 35,000
magnification)-

3. SEM (Repeat) Pd
Nanoparticle
Octahedron Shape (2
weeks and 4 days):
• Size of Pd
nanoparticle
is 10µm at
1,500
magnification
• About 100X’s
too large if
needing
100nm in size

4. Conclusion:
• Leave in solution for at least a week
before taking SEM images to allow
nanoparticles to grow on their individual
crystallographic planes.
• And look for nanoparticles at a higher
magnification than X35,000.
