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...

This review describes the synthesis and characterization of inorganic materials containing polyoxometalates encapsulated in oxide matrices. Examples illustrating key aspects in terms of synthesis and applications are presented according to the nature of the final hybrid material: those based on non-structured silicas, on mesostructured silicas, on macrostructured silicas and on other oxides. In...

Zwitterions and polyoxometalates (POMs) are two kinds of functional moieties with very different properties for applications in different fields. We have developed an effective strategy to successfully immobilize these two different moieties into the frameworks of porous hybrid materials, in which the POM units act as templates and photoactive moieties. These hybrid materials demonstrate remark...

H [PV Mo O ] catalyzed oxidation of thiols to related disulfides under microwave irradiation(MW). 5 2 10 40 Hydrogen Peroxide as an oxidizing reagent under mild conditions carried out this reaction. This system provides an efficient convenient and practical method for the syntheses of symmetrical disulfides. In this work, the comparisons among the Keggin and Dawson type polyoxometalates are add...

Transition-metal substituted Keggin-type polyoxometalates (POMs) are of great interest for applications in biomedicine, material science and catalysis. The synthesis transition metal-substituted polytungstates via the formation a lacunary...

a new efficient and practical method for the room-temperature reduction of aromatic nitro compounds employing feso4. 7h2o, nabh4, h3pw12o40 system in h2o under mild conditions is reported. the method is simple, inexpensive, easily scaled-up and applicable for the large scale preparation of different substituted anilines.
