Electrocatalysis

, 2010
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.
