Single-site, Ni-modified Wells–Dawson-type polyoxometalate for propylene dimerization

Propylene dimerization to linear products on isolated Ni2+ sites of modified Wells–Dawson-type polyoxometalates.

Immobilization of polyoxometalates in crystalline solids for highly efficient heterogeneous catalysis

The recently developed strategies on POM-based crystalline solids and their catalytic properties are summarized in this short review.

A multi-component polyoxometalate and its catalytic performance for CO2 cycloaddition reactions

A multi-component polyoxometalate based on earth-abundant elements (NH₄)₁₀[Co₈(H₂O)₁₀V₁₀Mo₂₃O₁₀₄(OH)₆]·34.5H₂O was obtained, which can prompt the coupling of CO₂ with epoxides.

Synthesis of a poly-pendant 1-D chain based on ‘trans-vanadium’ bicapped, Keggin-type vanadtungstate and its photocatalytic properties

A vanadtungstate cluster-based organic–inorganic hybrid material [NiL₄V^IVW^VI₁₀W^V₂O₄₀(V^IVO)₂] was synthesized, which not only serves as an active photocatalyst for the degradation of dye molecules, but also exhibits selective photocatalytic degradation of cationic dyes in aqueous solution.

From 1D to 3D single-crystal-to-single-crystal structural transformations based on linear polyanion [Mn4(H2O)18WZnMn2(H2O)2(ZnW9O34)2]4-

A 1D anionic polyoxometalate, [Mn(4)(H(2)O)(18)WZnMn(2)(H(2)O)(2)(ZnW(9)O(34))(2)](4-), undergoes 1D to 3D single-crystal-to-single-crystal structural transformations that are induced by transition-metal cations (Co(2+) and Cu(2+)) and solvent molecules. These solid materials present interesting catalytic activity for the oxidative aromatization of Hantzsch 1,4-dihydropyridines that is dependent on the inserted heterogeneous metal cations.
