Electrocatalysis

Electrocatalysis is a core field of interfacial science because it involves enhancement of reaction rates as in the case of heterogeneous catalysis, with an additional control through the variation of electrode potential. Electrocatalytic rates are influenced by the electrode potential either directly or indirectly. Because of increasing significance of green chemistry and clean energy with an intimate relationship between heterogeneous electrocatalysis and electrochemical energy conversion (batteries and fuel cells), the field of electrocatalysis has grown rapidly. In this article, basic concepts of electrode kinetics to assess electrocatalysis, and catalytic aspects of a few important electrochemical reactions are reviewed.
