Mesoporous structure characterization of nanoparticles.
| Sample | SBET (m2/g) | Vt (cm3/g) | DBJH (nm) |
|---|---|---|---|
| MSNs | 1138.73 | 1.28 | 3.73 |
| Py@MSNs | 543.45 | 0.59 | 3.48 |
| Py@MSNs-HTCC | 29.02 | 0.22 | 59.79 * |
| Py@MSNs-HTCC calcined | 960.17 | 1.14 | 3.88 |
* The silica nanoparticles lost their mesoporous structure characteristics after HTCC coating.
SBET: Brunauer–Emmett–Teller (BET) surface area; Vt: total pore volume; DBJH: Barrett–Joyner–Halenda (BJH) pore diameter.
