| Abstract: | The Oxidation-reduction behaviour of H3PMo12O40, M3PMo12O40 (M = NH4, Na, K), H4PMo11VO40 and M,H4-RPMo1jVO40(M = Na, La, K, Eu; n=1-4 for Na and La,n=4 for K, n= 2 for Eu) with a Keggin structure was studied by an electrochemical method in the mixed solvents of water-dioxane containing supporting electrolyte of 0. 5 mol/L H2SO4. The molybdenum in the acids and in their salts can gain or lose eight electrons, the vanadium in them can gain or lose one electron. The order and reversibility of oxidation- reduction for molybdenum and vanadium were also analyzed. |
