| 摘 要： | 采用电化学方法研究钛和过氧钛三取代：α—K8H2[SiW9TiO40]·15H2O，β-K7H3[SiW9Ti3O40]·15H2O，α—K9H2[SiW9（TiO2）3O37]·12H2O，β—K8H2[SiW9（TiO2）3O37]·10H2O，K9[PW9Ti3O40]·5H2O和K9[PW9（TiO2）3O37]·10H2O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的氧化性。对于Keggin结构的同一类型杂多配合物当中心离子不同时对其氧化性有影响。当中心离子为P时其氧化性强。对同一类型杂多酸盐，当为α和β两种异构体时，一般β型的氧化性大于α型。

| Abstract: | The studies on redox propertyes of titanium and peroxotitanium tri - substituted heteropoly with Keggin structure：α - K8H2 [ SiW9Ti3O40 ] · 15H2O,β - K7H3 [ SiW9Ti3O40 ] · 15H2O, K9 [ PW9Ti3O40 ] · 5H2O, α - K9H2 [ SiW9 （TiO2）3O37]· 12H2O,β- K8H2[SiW9（TiO2）3O37] · 10H2O和 K9[PW9（TiO2）3O37 ]·H2O were studied by electrochemistry methods. The experiment results indicated that the oxidizing property of peroxotitanium heteropoly complexes were better than oxidizing property of titanium heteropoly complexes. In the same isomers of peroxotitanium containing heteropoly com- plexes oxidizing properties of β - isomer was better than oxidizing properties of α - isomer. |
