Hyper-Cross-linked Porous MoS<sub>2</sub>–Cyclodextrin-Polymer Frameworks: Durable Removal of Aromatic Phenolic Micropollutant from Water
A reasonable
and efficient strategy for the construction of hyper-cross-linked
porous MoS<sub>2</sub>–CD-polymer frameworks (MoS<sub>2</sub>CDPFs) was demonstrated. Here, MoS<sub>2</sub> nanosheets (NSs) can
be decorated with amino functionalized β-cyclodextrin, producing
a nanoscale structural motif (MoS<sub>2</sub>@CD) for the synthesis
of MoS<sub>2</sub>CDPFs. We demonstrated that CD polymer (CDP) as
linker can be uniformly incorporated into the frameworks. Except for
the pores created between MoS<sub>2</sub> NSs, polymer doping generates
extra interspace between MoS<sub>2</sub> NSs and CD monomer. Interestingly,
the resultant MoS<sub>2</sub>CDPFs can rapidly sequester aromatic
phenolic micropollutant bisphenol A (0.1 mM) from water with 93.2%
adsorption capacity, which is higher than that of MoS<sub>2</sub>,
MoS<sub>2</sub>@CD, and CDP. The intercalation between MoS<sub>2</sub> sheets with CDP imparts the frameworks durability in adsorption/desorption
of aromatic phenolic micropollutants. Remarkably, the removal efficiency
reduced only 3% after 10 regeneration–reuse cycles. These findings
demonstrated that the porous MoS<sub>2</sub>–CD-polymer-based
frameworks are promising adsorbents for rapid, flow-through water
remediation
