Abstract

This chapter focuses on the particular role of the electrostatic potential on the self-organization phenomena of reactions at the solid liquid interfaces. For this purpose, a parallel will be established between the spatiotemporal dynamics of a gas-phase reaction, CO oxidation on Pt, and two electrochemical reactions. The electrochemical reactions are the electrooxidation of CO on Pt, an S-shaped negative differential resistance (NDR) system where the interfacial electric potential is involved in a negative feedback loop, and the H2 electrooxidation, an example of an (H)N-shaped-NDR system where the interfacial electric potential is involved in a positive feedback loop. The chapter presents the bistable and oscillatory behaviors of these reactions. It is devoted to the formation of self-organized patterns in spatially extended systems with a special emphasis put on CO electrooxidation as a prototypical model system in electrocatalysis, which, in addition, exhibits the richest variety of self-organization phenomena observed in an electrochemical reaction so far.
