- Abstract
- Enormous efforts have been put to effectively treat or eliminate toluene, one of the most well-known volatile organic compounds (VOCs). Herein, we report its sorptive removal mechanism against metal organic frameworks (MOFs: UiO-66, UiO-66(NH2), ZIF-67, MOF-199, MOF-5, and MIL-101(Fe)) under ambient conditions. Their interactions were assessed by the Henry's law constant (K-H) and the heat of adsorption (Delta H-ads). Although the equilibrated adsorption capacities of all MOFs were measured from 159 (MOF-199) to 252 mg g(-1) (UiO-66(NH2)), those values were reduced considerably with increases in humidity and temperature. Among them, the sorption pattern of UiO-66(NH2) was the most reproducible when tested over a three cycle (147 (1st) and 133 mg g(-1) (3rd cycle)). The behavior of -NH terminated MOFs (UiO-66(NH2) and ZIF-67) was distinguished with those of -COOH as explained by a scheme of hypothetical potential energy profiles using mass transfer resistance and surface barrier phenomena.
