Abstract
Solid electrolytes can act as active catalyst supports to induce the e ffect of Non-Faradaic Electrochemical Modification of Catalytic Activi ty (NEMCA). The main features of NEMCA are summarized together with so me new results on C2H4 epoxidation on Ag/YSZ and CO oxidation on beta' '-Al2O3. In situ XPS investigation of Pt/YSZ has confirmed that NEMCA is due to an electrochemically controlled ion spillover from the solid electrolyte onto the metal electrode surface.
