Özet:

 

Actually, lead dioxide (PbO2) is used as electrodes (cathode) in electrochemical power generators in particular in car batteries. The synthesis of lead dioxide is essentially obtained by chemical or electrochemical oxidation of lead salts processes. A very ambitious objective of this study is based on preparing lead dioxide by a newly developed method carried out in our laboratory. This consists in a first step to deposit a conductive polymer film poly[4-(pyrrol-1-yl methyl) benzoïc acid] having complexing properties performed by electrochemical oxidation in acetonitrile medium of the monomer 4-(pyrrol-1-yl methyl) benzoïc acid on the surface of a substrate such as carbon felt having a very high specific surface. In a second step, we proceed to the incorporation of lead dioxide by complexing the metal cations of lead in the polymer film performed by immersion of the modified electrode in a solution of lead nitrate to complex the Pb2 + cation with the carboxylic group COOH present in the polymer structure followed by electrooxidation in a solution free of lead to precipitate lead dioxide into the polymer in the form of metal microparticles. This material is used as the cathode material in batteries.
