Abstract:

The kinetics of photochemical reactions in aqueous polymer-salt systems containing ammonium heptamolybdate, dodecatungstate, or metavanadate and polyvinyl alcohol or polyvinylpyrrolidone was studied by measurements of photoinduced electrode potential difference. The rate of primary accumulation of reduced d metal forms was evaluated for different systems. Possible reasons for complex oscillatory processes in the systems were analyzed. Comparative data were obtained for compositions containing polyoxometallate shaped like buckyball: (NH(4))(42){[}Mo(72)(VI)Mo(60)(V)O(372)(HCOO)(30)(H(2)O)(72)] center dot 30HCOONH(4) center dot 250H(2)O. UV irradiation of this system caused the oxidation of molybdenum(V).
