The design and synthesis of a bifunctional catalyst to tackle environmental pollution caused by 2-chloroethyl ethyl sulfide (CEES) and phenolic compounds is meaningful. In this study, a new three-dimensional (3D) polyoxovanadate (POV)-based metal-organic framework, [Co(L)(V 4 O 12 ) 0.5 (H 2 O)]•2H 2 O (1; L = N,N'-bis(3methylpyridin-3-yl)-2,6-naphthalenediamide), was synthesized under hydrothermal conditions. 1 was characterized using single-crystal Xray diffraction analysis, infrared spectroscopy, and powder X-ray diffraction. Structural analysis shows that the [V 4 O 12 ] 4-clusters and pairs of Co 2+ cations are alternately connected to form a onedimensional inorganic chain, eventually generating a 3D (4,4)connected framework through the expansion of L, which exhibits a two fold interpenetration array. As a bifunctional catalyst, 1 exhibits satisfactory catalytic properties for the selective oxidation of 2-chloroethyl ethyl sulfide to the corresponding sulfoxide, with an effective conversion of > 99% and selectivity of 97%. Furthermore, 1 exhibits excellent photocatalytic degradation activity toward phenol, 2-chlorophenol, and m-cresol under visible light. The degradation efficiencies were above 92.6% for 140 min. The photocatalytic reaction kinetics, mechanisms of photodegradation, and recycling capability of phenol were also investigated in detail.

“…Polyoxometalate (POM), because of their fascinating structural and chemical versatility, are a recognizable choice in many fields of science, ranging from functional materials and catalysis to magnetism and biomedicine [1][2][3][4][5][6][7]. Metal-organic frameworks (MOFs), which are a class of crystalline porous materials constructed from metal ions and organic bridging ligands, lead to highly uniform porous structures with large surface areas [8][9][10][11][12][13].…”

The application of polyoxometalate (POM) as building blocks to construct chiral POM-based functionalized frameworks remains a long-standing challenge. In this study, we report a chiral assembly by blending inorganic POMs and organic cyclodextrin (α-CD) molecules on the basis of coordination interactions. {SiW 12 } anions connect with Mn ions (Mn 2+ ) antiparallel to form a unique allinorganic layer with significant voids. The similar α-CD layered structure fills the voids of the POM-Mn layers, which are interwoven to form an organic-inorganic hybrid, which is extended by Na + ions to produce a three-dimensional framework. The stability, chiral separation, chiral catalysis, and proton conductivity of this composite framework are explored.

“…Polyoxometalates (POMs) are a class of metal-oxo clusters with diverse structures and excellent properties and they have potential application in photochemistry, catalysis, proton conductivity and magnetism. 1–4 According to the literature on POM chemistry, in the last two centuries, V-, Mo- and W-based POMs have rapidly developed because they can be synthesized from simple materials (such as Na 3 VO 4 , Na 2 WO 4 or Na 2 MoO 4 ) through acidification, and their stable pH range is relatively wide. 5 On the contrary, POTa clusters are less studied, which may be attributed to several reasons: (a) soluble precursors of POTa are rare.…”
