摘要
制备了钨钴酸根与钨铜酸根阴离子掺杂的聚吡咯膜电极，并对其电化学行为进行了初步研究。结果表明，在微酸性或近中性的溶液中，该电极有良好的电化学稳定性及循环伏安行为。聚吡咯膜对钨铜酸根阴离子的第２个氧化还原过程有明显的催化作用。电子自旋共振显示杂聚阴离子与聚吡咯分子链形成了某种复合物，此复合物对聚吡咯电结构的影响随阴离子的不同而异。
Polypyrrole film electrode with Co(W_2O_7)_6￣(10-)and C uW_(12)_O_(40)￣(6-)ions were synthesized in aqueous solutions, The electrode possesses a good stability and cyclic voltammetric behavior in weakly acidic or near neutral solutions.The redox of CuW_(12)O_6￣(10-) ion can be catalysed by the polypyrrole film. The ESR measurement of the polypyrrole film with Co(W_2O_7)_6￣(10-)and CuW_(12)O_6￣(10) ions indicates that the heteropolyanions not only play the role of neutralizing electricity in the polypyrrole film,contrasted with the film containing NO but also interact with the polypyrrole molecular chain to form some additive compound. The additive compound affects the electric structure of the polypyrrole film and is unstable at more positive or more negative potentials.
