| Abstract: | The redox properties of molybdovanadophosphoric acid H6+n[P2Mo18-nVnO62]·H2O(n=1~3) and H4+n[P2Mo13-nVnO62H2]· H2O(n= 4,5) in solution were studied with potentiotitrimetry and polarography and cyclic voltammetry. The three reduction steps for the five heteropolyacids involving n, 2, 2 electrons accompanied by the addition of n, 2,2 protons were ascertained. The correlograms of the cyclic voltammogrammetric peak potentials versus pHwere obtained and the reduction mechanism has been proposed. |
