Shape-Evolution and Growth Mechanism of Fe3O4 Polyhedrons
Table 1
The experiment condition and growth mechanism of typical Fe3O4 morphologies.
| ā | Experiment condition | Growth mechanism |
| Plate | Extremely low reductant concentration | Extremely slow nucleation and growth rate |
| Octahedron | Low concentration of NaOH and reductant | Slow generating speed of Fe(II) |
| Decahedron | High concentration of NaOH and reductant | Fast generating speed of Fe(II) |
| Sphere | Extremely high NaOH concentration | Extremely fast nucleation and growth rate |
