| 摘 要： | 用循环伏安法在导电玻璃(ITO)和玻碳电极(GC)上制备了聚氨基酞菁钴(CoTAPc)修饰电极(CoTAPc/GC)。探讨了pH值对CoTAPc膜的光谱和电化学性质的影响，发现其氧化还原电位与pH值有线性关系，电催化活性也随酸度的增加而增加。CoTAPc膜的紫外吸收带变化与溶液pH值及在溶液中浸泡时间有关。

| Abstract: | The polymeric Cobalt tetraaminophthalocyanine (poly-CoTAPc) film was prepared by anodic electropolymerization on glass carbon electrode and conductivity glass (ITO) electrode. The electrochemistry and electronic absorption spectra of the ploy-CoTAPc film in B-R buffer solution were studied, which was related to the acidity of the solution. The redox potentials were found to be pH dependent. Electrocatalytic ability increased with increasing acidity. Acidity of the solution affects the position of spectral band, and absorbency increases with the increase of time soaked. |
