Construction of Sb-capped Dawson-type POM derivatives for high-performance asymmetric supercapacitors

Six polyoxotungstate-based transition metal compounds for electrochemical capacitor application and a comparative analysis of factors affecting capacitances

“…[15][16][17] However, their high solubility in various solvents limits their application as electrode materials. To address this problem, scientists came up with the idea of grafting POMs onto conductive carbon materials or polymers, for instance POM/graphene, [18][19][20] POM/CNTs, [21][22][23] POM/active carbon materials, 24 POM/PANI 25,26 and POM/PPy 27,28 (polyaniline and polypyrrole) have been synthesized as electrode materials for supercapacitors with breakthroughs. Nevertheless, the aforementioned POM materials also have disadvantages such as a low specific capacitance, poor conductivity or poor stability and do not take full advantage of POMs' structural diversity.…”

Polyoxometalate-based metal–organic supramolecular architectures derived from two new pyrimidine-amide ligands as supercapacitors and multifunctional electrochemical sensors

“…In contrast, the combination of POMs as inorganic building blocks with metal-organic complexes by hydrothermal or solvothermal methods is an effective strategy to modulate the function of POMs. 23,24 As a stable cluster, POMs can maintain their structural integrity during the reaction, which not only retains the original unique physical and chemical properties of POMs, but also avoids some of the shortcomings mentioned above. In addition, the synergistic effect between POM clusters and metal-organic units can also improve the stability and conductivity of these multifunctional materials, thereby further optimizing their electrochemical performance.…”

Combination of covalent organic frameworks (COFs) and polyoxometalates (POMs): the preparation strategy and potential application of COF–POM hybrids

“…Their work not only expands the class of Dawson-type {P 2 Mo 18 } derivatives but also provide ideas for improving the performance of POMs-based energy storage device. 100 POMs have unique photoactive properties that enable them to convert light energy into chemical energy. They can be used as photocatalysts for various reactions such as water splitting, dye degradation, and organic synthesis.…”
