Summary: The incorporation of polyoxometalates (POMs) in metal-organic frameworks (MOFs) with host-guest structure has been proven as an effective strategy for the rational design of heterogeneous catalysis. In this study, composite catalysts of Keggin-type POM@MIL-101(Cr) (PMo12, PW12, and SiW12) were synthesized for the first time for nitrogen fixation reaction without sacrificial agents at room temperature. The performance of the solvothermal synthesized catalyst was 75.56 lmol·h-1·g-1 Na4SiW12O40, attributed to the synergistic effect of SiW12 and MIL-101(Cr). This work provides a feasible route for designing and synthesizing nanocomposite materials with exceptional performance for photocatalytic nitrogen fixation.

Summary: The reaction of a rigid trisimidazole-based ligand with different auxiliary O-donor ligands resulted in five trisimidazole-based coordination polymers. The presence of different organic anions plays important roles in the formation of the final structures of the coordination polymers, leading to structural discrepancies among compounds 1-5. Furthermore, the thermal stabilities and photoluminescence properties of these compounds in solid state were also investigated.

Summary: In this study, novel PW12@MOF-808 and PW11@MOF-808 composites were successfully prepared by simple encapsulation method under compatible reaction conditions. The loading of POMs increased the accessible active sites and showed excellent catalytic activity for the oxidative desulfurization of dibenzothiophene (DBT). The catalyst demonstrated recyclability without significant loss in activity.

Summary: This article presents a series of new polyoxometalates (POMs) containing a Mo4O4 core. The new cluster exhibits the same Td symmetry as the classic Keggin POM, but with a higher nuclear number and more heterometal atoms due to its large Mo4O4 cubane template. Additionally, the third-order nonlinear optical (NLO) properties of these POMs are also investigated.

Summary: Zeolitic imidazolate frameworks (ZIFs) have been developed to mimic the structural characteristics of zeolites, with high surface area and adjustable pore size being their main features. The emerging hybrid zeolitic imidazolate frameworks (HZIFs) combine the advantages of zeolites and ZIFs, such as high stability and porosity. HZIFs find wide applications in electrocatalysis, photocatalysis, and ion storage, contributing to the progress in material chemistry, coordination chemistry, and structural chemistry.

Summary: In this study, we assessed the ability of Keggin type polyoxometalates (POMs) to bind cesium (Cs+) and compared it with the binding ability of sodium tetrakis(4-fluorophenyl)-borate (Na-TFPB). The results showed that the removal of Cs+ by POMs was more effective than TFPB, indicating that POMs could be a promising method for treating radioactive cesium contaminated soil.
