Modified Mn substituted POMs: Synthetic strategies, structural diversity to applications

Factors governing the protonation of Keggin-type polyoxometalates: influence of the core structure in clusters

“…1,[13][14][15][16][17] Protonation and deprotonation of POMs, which occur under acidic and basic conditions or in situ, are extremely important for their catalytic activities in many reactions, such as hydrogenation, dehydrogenation, oxygen reduction and hydrogen evolution, [18][19][20] and for model materials of molecular adsorption-desorption stimuli. [19][20][21][22][23][24] The redox behaviour of nanoclusters, as well as POMs with protonation and deprotonation, has been extensively investigated under various acidic and basic conditions. [25][26][27][28][29] Tuning protonation and deprotonation properties based on control of the coordination environment may broaden the range of POM applications.…”

Designing diverse coordination modes for the covalent attachment of Wells–Dawson type polyoxometalate onto porphyrins

“…For this reason, porphyrins have been bonded covalently with fullerenes, carbon nanotubes, and other organic and inorganic compounds. [7][8][9][10] As POMs are a vast group of outstanding electron acceptors 11 and the negatively charged metallic oxides exhibit structural diversity, [12][13][14] marvelous redox potentiality, 15 and attain-able organic grafting, 16 they have promising usefulness in the fields of magnetism, 17,18 catalysis, 19,20 optics, 21,22 production and storage of energy, [23][24][25] and medicine. [26][27][28][29] The development of POMs and their hybrids with organic moieties have received considerable attention.…”

Investigation on the Mechanism of Radical Intermediate Formation and Moderate Oxidation of Spiro-OMeTAD by the Synergistic Effect of Multisubstituted Polyoxometalates in Perovskite Solar Cells

“…Polyoxometalates (POMs), a type of inorganic metal–oxygen clusters that combine the properties of strong electron acceptability , and tunable chemical situation, , have attracted extensive attention in the fields of catalysis and photovoltaic conversion . Among them, Keggin-type POMs have been most widely studied due to their stable structures and relatively simple preparation process. The abundant high-valence transition metals (such as Mo 6+ , V 5+ , and W 6+ ) distributed at the periphery of the structure of Keggin-type POMs were surrounded by plenty of empty d-orbitals, , which allows them to accept multiple electrons from Spiro-OMeTAD.…”
