氧化还原聚合物修饰电极用于NO_2^-催化还原的探讨

Discussion on the Redox Polymer Modified Electrodes and Nitrite Reduction

氧化还原聚合物修饰电极因具有三维反应空间以及多相微结构而具有良好的反应选择性及催化活性。它对由ＧＣ／ＡＱ／Ｏｓ （ｈｐｙ）_（３）^（２－）阳离子交换聚合物及ＰＶＰ阴离子交换聚合物组成的双层聚合物复合修饰电极的电化学特性及对酸性溶液中ＮＯ_２~－的催化还原特性有重要作用。

Redox polymer modified electrodes have received increasing attention because of their increased catalytic emciency due to the three dimensionally distributed mediator centers and heterogeneous micro-structures of polymer. It plays an important role in the electrochemical properties of Gc/AQ/Os (bpy)3 and Gc/AQ/Os (bpy)/pvp modified electrodesd and the nitrite reduction properties at these modified electrodes.
