Electrocatalysis on polymer-modified electrodes

The procedures for applying polymeric films onto conductive supports and doping them with active microparticles of metal-catalysts or functional redox groups are considered. General principles of the electrocatalytic action of these systems are discussed. Experimental results on the electrocatalysis on electrodes modified by polymeric films are analysed. Attention is drawn to systems involving particles of platinum-group metals incorporated into polymeric matrices. The properties of electrodes modified by ion-conducting and electron-conducting polymers are compared. Certain problems to be solved in future studies of the electrode systems under discussion are formulated. The bibliography includes 265 references.
