Due to their capability of reversibly accepting multi lithium ions, polyoxometalates (POMs) have been widely regarded as promising candidates for electrochemical storage. Nevertheless, the insulating nature POMs hinders fast migration kinetics within bulk these materials. Herein, we propose introduction a local electric field surrounding POM nanoparticles consisting Mn and V where concomitant C...

This work reports the elaboration and structural study of new hybrid organic-inorganic materials constructed via the coupling of liquid-crystalline nonionic surfactants and polyoxometalates (POMs). X-ray scattering and polarized light microscopy demonstrate that these hybrid materials, highly loaded with POMs (up to 18 wt %), are nanocomposites of liquid-crystalline lamellar structure (Lalpha),...

With the increasing concerns to energy shortage and environmental problems in modern society, development of cheap, clean, sustainable alternatives has been attracting tremendous attention globally. Among various strategies renewable exploration, solar-driven water splitting into its compositional elements H2 O2 is an ideal approach convert store solar chemical bonds. In recent few decades, as ...

An efficient stepwise synthesis method for discovering new heteromultinuclear metal clusters using a robotic workflow is developed where numerous reaction conditions constructing oxo in polyoxometalates (POMs) were explored custom-built automated platform. As result, nonanuclear tetrametallic {FeMn4}Lu2A2 TBA5[(A-α-SiW9O34)2FeMn4O2{Lu(acac)2}2A2] (IIA; A = Ag, Na, K; TBA tetra-n-butylammonium; ...

The Cs-effect states Cs has more covalent character in bonding interactions than the lighter alkalis. It is exploited in organic synthesis and influences behavior in water, most notably radioactive Cs in nuclear wastes or the environment. Niobium polyoxometalates (Nb-POMs) provide a unique opportunity to probe aqueous phase ion-pairing responsible for cesium’s solution behavior, because Nb-POMs...

In recent years, carbon nanotubes (CNTs), including N-doped ones (N-CNTs), have received significant attention as supports for the construction of heterogeneous catalysts. this work, we summarize our progress in application (N)-CNTs immobilization anionic metal-oxygen clusters or polyoxometalates (POMs) and use (N)-CNTs-supported POM catalysts liquid-phase selective oxidation organic compounds ...

In recent years, due to the impact of global warming, environmental pollution, and energy crisis, international attention demand for clean are increasing. Hydrogen is recognized as one sources. Water considered largest potential supplier hydrogen energy. However, artificial catalytic water splitting oxygen evolution has not been widely used its high consumption cost during cracking. Therefore, ...

Polyoxometalates (POMs) are clusters of units oxoanions transition metals, such as Mo, W, V and Nb, that can be formed upon acidification neutral solutions. Once formed, some POMs have shown to persist in solution, even the basic pH range. These inorganic clusters, amenable a variety structures, been studied environmental, chemical, industrial fields, having applications catalysis macromolecula...

• POMs were nano-dispersed within MXene with assistance of AC matrix. The hybrid combined the merits and compensate for demerits each component. Gravimetric capacitance was 2.2 times that MXene. remained anchored in long-term leading to great cycle stability. Hybrid's asymmetric cells outperformed AC//MXene by weight volume. We report a triple electrode (MXene/activated carbon (AC)/polyoxometal...

The interaction between human serum albumin (HSA) and a series of Zr(IV)-substituted polyoxometalates (POMs) (Lindqvist type POM ((nBu4N)6[{W5O18Zr (μ-OH)}2]·2H2O, Zr2-L2), two Keggin type POMs ((Et2NH2)10[Zr(PW11O39)2]·7H2O, Zr1-K2 and (Et2NH2)8[{α-PW11O39Zr(μ-OH)(H2O)}2]·7H2O, Zr2-K2), and two Wells-Dawson type POMs (K15H[Zr(α2-P2W17O61)2]·25H2O, Zr1-WD2 and Na14[Zr4(P2W16O59)2(μ3-O)2(OH)2(H2...
