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, ...

Hybrid hydrogels based on electrostatic co-assembly of polyoxometalates and ABA triblock copolymers were readily prepared and exhibit excellent luminescence and self-healing performance.

We have demonstrated that a pentaerythritol-derivatized hexavanadate can be easily esterified with acid anhydrides using 4-(N,N-dimethylamino)pyridine (DMAP) as a catalyst, which provides a convenient method for the functionalization of polyoxometalates.

A new approach for the chemical modification of the surface of paper based on the application of colloidal mixtures containing cationic starch and polyoxometalates on uncoated base paper is presented. Polyoxometalates with the Keggin-type structure and physical properties similar to those presented by coating pigments, namely H3PW12O40·23H2O, H4SiW12O40·24H2O, and K7PW11O39·9H2O, have been used...

Transition-metal-substituted  (TMS)  polyoxometalates  of  the  general  formula  [SiW9M3O39], (where M = first row transition metal), has been synthesized and supported on anatase by sol–gel method under oil-bath condition. The tetrabutylammonium (TBA) salts of the Keggin-type polyoxotungstates  [SiW9M3O39],  (M = VII, CrII, MnII,  FeII CoII  and NiII),  proved  to  be  green, reusable,  and  ...

The presence of alkylammonium groups covalently grafted on bisphosphonato ligands induces photochromic properties to ligand-coordinated polyoxomolybdate systems. Such intrinsically photoactive polyanions can be used for the preparation of materials combining photochromic polyoxometalates and functional countercations.

In the last decade organic-inorganic hybrid materials have become essential in materials science as they combine properties of both building blocks. Nowadays the main routes for their synthesis involve electrostatic coupling, covalent grafting, and/or solvent effects. In this field, polyoxometalates (POMs) have emerged as interesting inorganic functional building blocks due to their outstanding...

the aerobic oxidation of alcohols was efficiently completed in high conversion and selectivity using cu3/2[pmo12o40]/sio2 as catalyst under mild reaction condition. this reaction provides a new environmentally friendly rout to the conversion of alcoholic function to carbonyl groups.

We report a novel design, based on a combination of lanthanide-doped upconversion nanoparticles and polyoxometalates, for electrically controlled fluorescence switches and sensitive detection of antioxidants in aqueous solution.
