Abstract
The redox properties of K 6PW 9V 3O 40 - a tungstophosphate substituted by three vanadium atoms at the 1, 2, 3-positions with Keggin structure are described. The oxidizability of this compound is much higher than that of the unsubstituted tungstophosphate. The three vanadium atoms in K 6PW 9O 40) can be reduced step-by-step and have better redox reversibility. The influence of the pH, ionic strength and solvent on the redox properties of this compound are also reported.
