| 摘 要： | 用光电化学方法研究了铜电极在含苯并三唑(BTA)的硼砂-硼酸缓冲溶液中的光电化学行为。BTA能使铜电极的光响应由p-型转变为n-型。产生光响应的原因是铜电极表面的Cu2O膜。当BTA存在时由于BTA的作用致使电极表面Cu2O膜中共存着p-型和n-型区域, 电位正移和频率增加导致电极显示n-型光响应。

| Abstract: | The photoelectrochemical behavior of copper electrode in borax buffer solutions containing benzotriazole (BTA) was studied by using photoelectrochemical techniques. The addition of BTA changes the photoresponse of the electrode from p-type to n-type. In the presence of BTA, both p-type and n-type regions heterogeneously coexist in the Cu2O film on the surface of Cu electrode, and it is shown from IMPS that more positive potential and higher chopping frequency are in favor of appearance of n-type photoresponse. |
