Surface area and size distribution of metallic nickel particles
| Nickel fine particles | Nickel nanoparticles | |
| Surface area (m2/g) | 0.4 ± 0.01 | 4.36 ± 0.02 |
| Average size | 3.34 ± 0.67 (μm) | 92.32 ± 29.69 (nm) |
Surface area was determined by gas absorption and particle size by scanning electron microscopy. Values are means ± S.E. of six independent assays.
