Electrocatalysis, conducting polymers

Electrocatalysis, (2009-2015) and is presently a member of the Editorial Board of Journal of Solid State Electrochemistry(Springer), of the International Journal of Electrochemistry (Endawi), Electrochemistry Communications, Journal of the Serbian Chemical Society, Electrochemical Energy Technology and Chimica Nova. He has contributed in several areas or electrochemistry including electrocatalysis, conductive polymers, electroanalysis, corrosion, electrochemistry of macrocyclic complexes and is better known for developing reactivity descriptors for the elec-trocatalytic activity of molecular catalysts. 

Conducting polymers have found applications in a wide variety of areas,44 45 and many more have been proposed. From an electrochemical perspective, the most important applications46 appear to be in batteries and supercapacitors 47,48 electroanalysis and sensors49-51 electrocatalysis,12,1, 52 display and electrochromic devices,46 and electromechanical actuators.53... 

Like other ion-exchange polymers, conducting polymers have been used to immobilize electroactive ions at electrode surfaces. Often the goal is electrocatalysis, and conducting polymers have the potential advantage of providing a fast mechanism for electron transport to and from the electrocatalytic ions. 

Among the several fields in which electronically conducting polymers are useful or may be so the future, are electrocatalysis, prosthetics, and electrodes suited for use with biomaterials, (d) Consider each of these areas and state the reasons you think electronically conducting compounds (those now available and those that may be synthesized) would have characteristic properties of special use in the areas mentioned.

The modification of electrode surfaces with electroactive polymer films provides a means to control interfacial characteristics. With such a capability, one can envisage numerous possible applications, in areas as diverse as electronic devices, sensors, electrocatalysis, energy conversion and storage, electronic displays, and reference electrode systems [1, 2]. With these applications in view, a wide variety of electroactive polymeric materials have been investigated. These include both redox polymers (by which we imply polymers with discrete redox entities distributed along the polymer spine) and conducting polymers (by which we imply polymers with delocalised charge centres on the polymer spine). 

In Chapter 24, Duo and coworkers discuss metal oxide nanoparticle reactivity on synthetic boron-doped diamond surfaces. Lamy and Leger treat electrocatalysis with electron-conducting polymers in the presence of noble metal nanoparticles, and new nanostructure materials for electrocatalysis are the subject of the final chapter, by Alonso-Vante.
