The electrochemical behaviour of polypyrrole coated electrodes has been examined by cyclic voltammetry. It has been found that polypyrrole coatedelectrodesare selective to F&+/Fe'+ couple but not to thionine/leucothionine couple. An improved output in the Iron-thionine photogalvanic celi has been ob

The role of electrode selectivity in the performance of the ferrous/thionine photogalvanic cell has been studied using various carbon materials as light electrode. The open-circuit voltage of the cell is found to depend strongly on the type of carbon electrode used. This dependency can be quantitati
The cyclic voltammetric deposition on metallic electrodes of multilayer coatings of the dyes thionine, oxonine, Nile Blue A and Neutral Red, and of l-hydroxyphenazine and 1-aminophenazine, is described. Evidence is presented to show that the coatings are produced by polymerization of oxidativelyform
