Facile Fabrication of Multifunctional Metal–Organic Framework Hollow Tubes To Trap Pollutants
Pollutant treatment
is critical in modern society and often requires
tedious workup and expensive facilities. By virtue of structural diversity
and tunability, metal–organic frameworks (MOFs) have shown
promise in pollutant control. We herein report a powerful templated
freeze-drying protocol for the fabrication of multifunctional MOF
hollow tubular structures for both air and liquid contaminants filtration.
Various hollow tube systems (e.g., “Janus”, “coaxial”
and “cellular”) are produced. Specially, a multilayer
coaxial MOF hollow tube is prepared for highly efficient capture of
mixed inorganic–organic liquid contaminants with >94% filtration
efficiency. Further, a “cellular” hollow tube with low
pressure-drop (12 Pa, 10 cm s<sup>–1</sup>) is applied in particulate
matter filtration with high efficiency (>92%). Given the rich structural
and functional diversities, this protocol might bring MOFs into industrial
applications to remediate environmental problems
