Non-Faradaic electrochemical modification of catalytic activity: solid electrolytes as active catalyst supports
Abstract Solid electrolytes can act as active catalyst supports to induce the effect of Non-Faradaic Electrochemical Modification of Catalytic Activity (NEMCA). The main features of NEMCA are summarized together with some new results on C 2 H 4 epoxidation on Ag/YSZ and CO oxidation on β″-Al 2 O 3 . 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.
