Layered aluminum-based metal-organic framework as a superior trap for nitrobenzene capture via an intercalation role

Abstract

Layered materials with porous layers are of great interest due to their intriguing structural topologies and potential applications as new adsorbents. In this study, a layered aluminum-based metal-organic framework, i.e. Al-TCPP, was successfully synthesized via a facile method for the adsorptive removal of nitrobenzene (NB). The as-synthesized Al-TCPP exhibited a typical layered structure and can be stable at pH ≈ 5-7. Batch experimental results showed a superior adsorption performance towards NB with a maximum capability of 1846.7 mg/g, and an exceptionally rapid equilibrium within 1 min. X-ray diffraction patterns of the samples after adsorption demonstrate the possible intercalation took place in layered Al-TCPP during the adsorption. After the capture of NB, the shape and crystallinity of Al-TCPP material basically retain the original status. This work highlights new prospects in designing layered materials for the use in environmental remediation.
