Textural parameters of the MSN materials obtained by N2 adsorption measurements.
| Material | SBET (m2/g) | Dp (nm) | VT (cm3/g) | VP (cm3/g) |
|---|---|---|---|---|
| MSNs | 1368.4 | 2.73 | 1.64 | 1.09 |
| MSNs-CTAB | 104.2 | --- | --- | --- |
| MSNs-COOHext | 557.2 | 2.03 | 0.391 | 0.274 |
| MSNs-LprG | 440.6 | 1.20 | 0.389 | 0.218 |
SBET is the specific surface area obtained by using the BET equation, DP is the pore diameter calculated by using the Barrett-Joyner-Halenda (BJH) method, VT is the total pore volume obtained at P/P0 = 0.99, and VP is the total pore volume obtained at P/P0 = 0.60.
