| 摘 要： | 以铂网栅电极作工作电极，设计制作了一种应用于紫外-可见光谱电化学研究的新型光透薄层电化学池（OTTLE），并以铁氰化钾-亚铁氰化钾体系对此光谱化学池进行了表征。铁氰化钾-亚铁氰化钾体系在该池中有良好的循环伏安特性，并可获得良好的紫外-可见光谱。测得的克式量电位E^0，电子转移数n与文献结果一致。

Fabrication and Evaluation of an Optically Transparent Thin Layer Platinum Minigrid Electrochemical Cell |
| |
| Abstract: | The design and construction of an optically transparent thin layer Pt minigrid electrochemical cell are described. The cell consists of a Pt minigrid working electrode, an Ag/AgCl reference electrode and a Pt wire auxiliary electrode. Application of the cell is illustrated by thin layer cyclic voltammetry and ultraviolet visible spectral electrochemical data on K 3Fe(CN) 6 system in aqueous 1 mol/L KCl supporting electrolyte. The value of the formal potential E 0' and the number of electron n of K 3Fe(CN) 6 couple determined by ultraviolet visible thin layer spectral electrochemical method are good agreement with those in literatures, which illustrates that the cell has fine spectral electrochemical characteristics. |
