摘    要:在NaNO3和吡咯单体的混合溶液中电合成聚吡咯膜,用PPy膜敏化TiO20纳米结构电极,取得了明显的敏化效果;探讨了合成聚吡咯膜时的条件(温度、时间、NO3浓度等)对敏化结果的影响;比较了在对甲苯磺酸根离子中与在NO3^-中合成PPy膜所产生的敏化效果,表明阴离子的类型和性质对敏化效果有很大影响;初步探讨了PPy膜对TiO2纳米结构电极产生敏化作用的机理。

关 键 词:TiO2纳米结构电极  光电化学  敏化  聚吡咯

Abstract:The film of polypyrrole was synthesized in the mixture of NaNO_3 and pyrrole,which was used to modify TiO_2 nanoscrystalline porous membrane electrode and obvious sensitizing effect was observed. The synthesizing conditions which contributed to effect of sensitization were also studied. the sensitization of electrode was studied by comparing the PPy film which was prepared in TsO~- with PPy film prepared in NO~-_3 electrolyte .The results showed that the type and propery of anion was greatly related to the effect of sensitization. The mechanism of sensitization effect of polypyrrole for TiO_2 nanocrystalline film electrode was investigated.
Keywords:TiO_2 nanostrctured electrode  photoelectrochemistry  sensitization  polypyrrole
