摘要
Highly porous metal-organic framework (MOF), MIL-101(Cr), was modified by introduction of polyaniline (PANI) via ship in bottle strategy in order to utilize basic moieties of PANI in capturing CO2 effectively from flue gas. [email protected](Cr), with suitable PANI concentration, showed highly increased adsorption capacity for CO2, especially at low pressure of 0.15 atm, even though the porosity of MIL-101(Cr) was decreased upon PANI loading. Moreover, the [email protected](Cr) showed increased selectivity for CO2 (against N2), compared with pristine MIL-101(Cr); and stable reusability. The observed favorable adsorption of CO2 on the [email protected](Cr) might be because of basic species on well-dispersed PANI on the MOF. The results indicate that modification of porous materials such as MOFs with PANI might be one way to improve performances for CO2 capture.
