Brunauer–Elmett–Teller (BET) surface area and pore volume for differently modified MNPs with respect to bare MNPs.
| BET Surface Area * (m2·g−1) | BJH Adsorption Pore Volume (cm3·g−1) | |
|---|---|---|
| MNPs | 13.56 | / |
| MNPs@SiO2 | 25.21 | 0.16 |
| MNPs@SiO2@GOPTS-bPEI | 38.33 | 0.23 |
* the BET surface areas are smaller compared to the calculated theoretical specific surface area due to the high degree of agglomeration during the drying process.
