| Abstract | ||||
| The electrochemical promotion of catalysis (EPOC), also known as non-Faradaic electrochemical modification of catalytic activity (NEMCA), is a rather general phenomenon observed in about 30 years ago. This phenomenon has a strong impact on modern electrochemistry, heterogeneous catalysis and surface science. The EPOC effect can be achieved with porous thin film electrodes interfaced to solid electrolytes. A dramatic improvement in the catalytic activity has been obtained by polarization of the interface via an electrical current or potential application. It has been studied for more than 100 catalytic reactions, including oxidations, reductions and isomerisations and using a variety of metal or metal oxide catalysts, and different types of solid electrolytes. In this review paper the main features and mechanisms of the electrochemical promotion effect are summarized and discussed. | ||||
