| Sample | SBET (a) (m2/g) | SLANG (a) (m2/g) | Smicro (b) (m2/g) | Vmicro (b) (cc/g) | Vtotal (c) (cc/g) |
|---|---|---|---|---|---|
| UiO-66 | 1733 | 2266 | 1662 | 0.809 | 0.938 |
| UiO-66-NH2 | 1218 | 1599 | 1160 | 0.569 | 0.682 |
| UiO-66-Br | 851 | 1117 | 818 | 0.380 | 0.440 |
| UiO-66-(OH)2 | 318 | 418 | 293 | 0.136 | 0.178 |
(a) BET surface area and Langmuir surface area (SBET and SLANG) were determined at P/Po = 0.05–0.2; (b) Micropore surface area and micropore volume (Smicro and Vmicro) were determined at P/Po = 0.4–0.6 using t-plot method; (c) Total pore volume (Vtotal) was determined at P/Po = 0.99.
