Table 1. Textural properties of the porous organic–inorganic hybrid, HybPyr, and pure silica materials.
Sample | BET surface area (m2 g–1) | External surface (m2 g–1) | Micropore volume (cm3 g–1) | Total pore volume (cm3 g–1) | Mean pore diameter (Å) |
HybPyr | 386 | 378 | 0.004 | 0.325 | 40 |
Pure silica | 668 | 547 | 0.053 | 0.473 | 20–30 |
