The catalytic activity and selectivity of metal films deposited on solid electrolytes can be altered dramatically and reversibly via the effect of Non-Faradaic Electrochemical Modification of Catalytic Activity (NEMCA). In the present paper we briefly summarize the main features of the NEMCA effect and present and discuss the existing kinetic, electrokinetic and surface spectroscopic evidence that NEMCA is due to an electrochemically induced and controlled ion spillover from/to the solid electrolyte to/from the metal catalyst surface.
