Fabrication of isoreticular metal-organic framework coated capillary columns for high-resolution gas chromatographic separation of persistent organic pollutants.
摘要：
The unusual properties of metal–organic frameworks (MOFs), such as permanent nanoscale porosity, high surface area, uniformly structured cavities, and the availability of in-pore functionality and outer-surface modification, are advantageous for diverse applications. However, most existing methods for the synthesis of nanosized MOFs require an activation procedure or auxiliary stabilizing agents. Here we report a 1-min, room-temperature approach for the synthesis of nanosized isoreticular MOFs (IRMOFs) to fabricate IRMOF coated capillary columns for the high-resolution gas chromatographic separation of persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), polybrominated diphenylethers (PBDEs), and hexachlorocyclohexanes (HCHs). The developed method allows the synthesis of well-shaped nanosized IRMOFs within 1 min at room temperature without the need for any activation procedure or auxiliary stabilizing agents. The IRMOF coated capillary columns...
