Two 3D Two-Fold Interpenetrated Dia-Like Polyoxometalate-Based Metal–Organic Frameworks: Synthesis and Sulfide Selective Oxidation Activity

“…However, its further application is limited due to its inherent shortcomings, such as high solubility and difficult separation. In order to realize the reusability of POM catalysts, one of the acceptable strategies for constructing POM-based heterogeneous catalysts is to select appropriate supports (such as metal oxides, COFs, graphene, nitrides, and metal–organic frameworks (MOFs)) and immobilize POMs. − MOFs have shown advantages over other porous supports in the structural design and mechanism study of POM-supported catalysts because of their clear composition and structure. − In this regard, our research group has done some pioneering work. A series of three-dimensional (3D) crystalline POM-based organic frameworks have been successfully synthesized and acted as heterogeneous catalysts for effective hydrolysis of esters, removal of nerve gases, oxidative desulfurization, etc. − Therefore, encapsulation of POMs into MOFs to construct POMOFs is an effective strategy to retain the intrinsic activity of POMs and endue heterogeneous catalytic properties.…”

Assembly of Lanthanide-Containing 3D [MnMo9O32]6–-Based Metal–Organic Frameworks and Oxidative Desulfurization Performance

“…However, the study of lanthanide-containing [MnMo 9 O 32 ] 6– compounds remains comparatively less . Undoubtedly, the introduction of Ln 3+ ions to MOFs or POMOFs has been significant and aroused increasing interest in recent years. − On one hand, the Ln 3+ can be used as nodes with the fashion of ions, chains, and clusters, promoting structural diversity. , On the other hand, the Ln 3+ features highly variable and tunable coordination numbers and modes, which makes the Ln-containing MOFs or POMOFs good candidates in the realm of catalysis. ,− Nevertheless, the Ln-containing MOFs or POMOFs are difficult to synthesize due to the high hydrolysis of Ln 3+ ions and the large electrostatic repulsion between Ln 3+ ions and polyoxoanions, which tend to cause precipitation and thus hinder the crystallization process. This inspired us to choose suitable organic ligands for the architecture, which can not only coordinate with Ln 3+ ions but also effectively control their slow hydrolysis .…”

Efficient dye degradation and THz spectra of {PMo12} based rare earth phosphine oxide complexes

“…In previous work, we have synthesized some rare earth complexes containing bisphosphonate ligands and characterized them by terahertz time-domain spectroscopy. 38–42 The THz test of the complexes provided data for the THz database and contributed to subsequent research.…”
