| Abstract: The studies on redox propertics of niobium and peroxyniobium substituted tungstophosphoric heteropoly complexes with Dawson structure: α2-MaHbP2W17NbO62·xH2O,α-1,2,3,-MaHbP2W15Nb3O62·xH2O,α2-MaHbP2W17(NbO2)O61·xH2O and α-1,2,3-MaHbP2W15(NbO2)3O59·xH2O(M=K, TMA,TEA.TBA)in aqueous solution were made by electrochemistry methods. The expcriment results indicate that redueed waves of peroxyions are in the range of 0.2-0.3V. the presence of peroxyniobium(NbO2)increases the oxidizing power of heteropoly complexes; the oxidizing power of complexes deercascs as niobium atom number increases. |
