STUDY ON PROPERTY OF MONO-SUBSTITUEDHETEROPOLY COMPLEXES WITH DAWSON STRUCTURE

采用电化学方法研究一取代K8[P2 W1 7TiO62 ]· 5H2 O ,K8[P2 W1 7ZrO62 ]·7H2 O ,K8[P2 W1 7(TiO2 )O61 ]· 9H2 O和K8[P2 W1 7(ZrO2 )O61 ]· 4H2 O的氧化还原性质 .实验结果表明 :过氧型杂多配合物的氧化性大于非过氧型杂多配合物的氧化 .Ti取代的杂多配合物的氧化性大于Zr取代杂多配合物的氧化性 .

The studies on redox properties of mono-substituted heteropoly complexes with Dawson structureK 8[P 2W 17 TiO 62 ]·5H 2O,K 8[P 2W 17 ZrO 62 ]·7H 2O,K 8[P 2W 17 (TiO 2)O 61 ]·9H 2O adn K 8[P 2W 17 (ZrO 2)O 61 ]·4H 2O were made by electrochemistry methods. The experimental results indicate that the oxidizing property of peroxo-heteropoly complexes are better than oxidizing property of heteropoly complexes. The oxidizing properties of Ti-substituted heteropoly complexesis better than oxidizing properties of Zr-substituted heteropoly complexes.
