Fractal dimension parameters as calculated by different methods from SEM images for both MoS2 and cobalt promoted MoS2 samples.
| Method of analysis | SEM-images at 1.0 µm | |
|---|---|---|
| MoS2 | MoS2 /Co | |
| D p | 1.64 ± 0.03 | 1.07 ± 0.02 |
| D B | 1.90 ± 0.01 | 1.37 ± 0.01 |
| D I | 1.92 ± 0.01 | 1.47 ± 0.01 |
| D M | 1.98 ± 0.01 | 2.02 ± 0.02 |
D P, D B, D I and D M are measured from TEM-images; D p scaling interval ∈ [1, 2]; D B scaling interval ∈ [1, 2]; D I scaling interval ∈ [1, 2]; D M ≥ 1.
