Polyoxometalates (POMs) have become very significant in biomedical research for their structural diversity which renders them highly active against bacterial, viral and cancer diseases. In this study three different POMs were synthesized and nanoassemblies were made with chitosan (CTS), a natural biodegradable polymer with excellent drug carrier properties. The compounds were tested on two isoe...

Polyoxovanadates (POVs) are a subclass of larger family polyanionic group V and VI metal-oxo clusters that known as polyoxometalates (POMs). POMs have been found to antidiabetic, antibacterial, antiprotozoal, antiviral anticancer activities, which sparked interest in their use bioinorganic drugs. Among POVs, decavanadate ([V10O28]6−; V10) is an isopolyoxovanadate recently described several medi...

Electrochemical CO2 reduction to value-added fuels and chemicals is recognized as a promising strategy alleviate energy shortages global warming owing its high efficiency economic feasibility. Recently, understanding the activity origin, selectivity regulation, reaction mechanisms of reactions (CO2RRs) has become focus efficient electrocatalyst design. Polyoxometalates (POMs), unique class nano...

Catalysis by Heteropoly acids (HPAs) and polyoxometalates (POMs) having a higher demand worldwide, as it can be designed to accelerate complex reactions more environmentally friendly. However, recycling of water-soluble solid catalysts remains problem. The synthesis recyclable composite with catalytic properties is the key better use HPAs POMs. Many researches have mentioned method immersing po...

This review is intended to provide an up-to-date and comprehensive description of recent advances since the mid-2010s in elaboration involvement polyoxometalates (POMs)-functionalized (photo)electrodes (photo)electrocatalytic reactions. Focus has been essentially placed not only on reactions high interest, such as hydrogen evolution reaction (HER), oxygen (OER), CO2 reduction (CDRR) but also ot...

In this work, a series of polyoxometalates (POMs), as soluble salts formula Sn1.5PMo12O40, SbPMo12O40 and H 3-x Sn x1 Sb x2 PMo 12 O 40 (x=2x 1 +3x 2 x , = 0–0.75) were synthesized using the cationic exchange method under stoichiometric conditions. They characterized tested in oxidation cyclohexanone hydrogen peroxide absence organic solvent, co-catalyst phase transfer compounds or surfactants....

Nb-containing polyoxometalates (POMs) of the Wells-Dawson class inhibit HIV-1 protease (HIV-1P) by a new mode based on kinetics, binding, and molecular modeling studies. Reaction of alpha(1)-K(9)Li[P(2)W(17)O(61)] or alpha(2)-K(10)[P(2)W(17)O(61)] with aqueous H(2)O(2) solutions of K(7)H[Nb(6)O(19)] followed by treatment with HCl and KCl and then crystallization affords the complexes alpha(1)-K...

It has been found that polyoxometalates (POMs) can act as mediators in the electrochemical oxidation of lignin in pulps. An electrochemical cell, with a Nafion membrane separating the anode and cathode compartments, was used in the delignification experiments. A softwood kraft pulp was placed in the anode compartment with a buffered 0.01M solution of the polyoxometalate Na5[SiVW11O40]. During e...

A cationic boron dipyrromethene (BODIPY) derivative (1+) has been successfully combined with two polyoxometalates (POMs), the Lindqvist-type [W6O19]2– and β-[Mo8O26]4– units, into three new supramolecular fluorescent materials (1)2[W6O19]·2CH3CN, (1)2[W6O19], (1)4[Mo8O26]·DMF·H2O. The resulting hybrid compounds have fully characterized by a combination of single-crystal X-ray diffraction, IR UV...

Polyoxometalates (POMs) are inorganic clusters that possess potential anti-bacterial, anti-viral, and anti-tumor activities. Herein, the in vitro anti-proliferation activities of K12[V18O42(H₂O)]∙6H₂O (V18) have been investigated on the MCF-7 and MDA-MB-231 cell lines. The results indicated that V18 could inhibit the proliferation of MCF-7 (IC50, 11.95 μM at 48 h) in a dose-dependent manner com...
