| 摘 要： | 研究了乙醇对双核酞菁钴(b i-CoPc)掺杂聚苯胺(PAn)膜修饰电极特性的影响。用循环伏安法(CV)考察了乙醇浓度不同时,玻碳电极(GC)上双核酞菁钴掺杂聚苯胺的电聚合过程,用紫外-可见吸收光谱(UV-V is)、红外光谱(FTIR)和扫描电子显微镜(SEM)表征了在氧化铟锡玻璃(ITO)电极上b i-CoPc掺杂的PAn膜,研究了乙醇对膜以及该膜修饰电极对溶液中分子氧电催化性能的影响。结果表明,乙醇对苯胺的电聚合有促进作用,有助于增加b i-CoPc掺杂量,膜的光谱特性发生变化,表面形貌更加均匀。乙醇存在下制备的修饰电极对溶液中分子氧的电催化活性明显提高。当乙醇含量为10%时,制备的电极催化能力最强。

| Abstract: | The electropolymerization of polyaniline(PAn) film in the presence of planar binuclear cobalt phthalocyanine(bi-CoPc) on different concentration of ethanol on glassy carbon electrode was examined by cyclic voltammetry(CV).The effects of ethanol on properties of films on indium-tin oxide(ITO) glass were investigated by CV,ultraviole-visible spectroscopy,Fourier transform infrared spectroscopy and scanning(electron) microscope.The results show that in the presence of(10%) ethanol which the electropolymerization rate was(enhanced),and the doping amount of bi-CoPc was increased,leads to finer structure of PAn film.It is found that the electrocatalytic activity of bi-CoPc-PAn modified electrodes towards oxygen reduction is higher in the presence of 10% ethanol than that of its absence. |
