Preparation and characterization of novel polyoxometalate/CoFe₂O₄/metal–organic framework magnetic core–shell nanocomposites for the rapid removal of organic dyes from water

Abstract

The magnetic CoFe2O4/MIL-101 (Cr) metal–organic framework nanocomposite containing P2W18O626− polyoxometalate was fabricated and applied as an ultrafast adsorbent to remove organic dyes from water.

Heterogenisation of polyoxometalates and other metal-based complexes in metal–organic frameworks: from synthesis to characterisation and applications in catalysis

“…This is the case for Eu(PW11)2@MIL-101(Cr) 64 and P2W18@MIL-101(Cr). 60 In the latter, the W=O band is shifted to lower frequency as a result of POM/MOF interactions (Fig. 10b).…”

Dye contaminated wastewater treatment through metal–organic framework (MOF) based materials

“…144 Farhadi et al core-shell MOF nanocomposites for the rapid removal of RhB, MO and MB from wastewater effluents. 145 POM/CFO/MIL-101(Cr) was synthesized by the hydrothermal method. This method was found to be very useful, economical, and efficient for the adsorption and separation of dyes through MOF composites.…”

POM-based compounds modified by mono- and bis-triazole derivatives: photocatalytic, electrochemical, and supercapacitor properties

“…Furthermore, organic dyes can cause serious water pollution. 23 The POM-based compounds have environmental protection significance for the photocatalytic degradation of organic dyes and the photoreduction of Cr(VI). Thus, it is meaningful to explore electrochemical sensing and photocatalytic properties of POM-based compounds.…”
