C NaOH = 0.01 mol (pH = 3) | Flower-like hierarchical structures,2 μm in diameter | 72.4 | 2.97 | 98.9 |
C NaOH = 0.03 mol (pH = 5) | Irregular flake-like structures, 55 nm in thickness | 33.7 | 2.97 | 92.7 |
C NaOH = 0.0545 mol (pH = 9) | Irregular flake-like structures, 60 nm in thickness | 18.2 | 2.97 | 69.5 |
C NaOH = 0.05525 mol (pH = 11) | Spherical structures, 85 nm in diameter | 9.5 | 2.93 | 45.8 |
