Non-faradaic electrochemical modification of catalytic activity
Non-faradaic electrochemical modification of catalytic activity (NEMCA effect),<ref name='10.1021/j100329a007'> </ref> also known as electrochemical promotion of catalysis (EPOC),<ref name='10.1007/s10800-009-9938-7'> </ref> is used to describe the increase in catalytic activity (up to 90-fold) and selectivity of a gas exposed electrode on a solid electrolyte cell upon application of a potential. This phenomenon is well documented and has been observed on various surfaces (Ni, Au, Pt, Pd, IrO2, RuO2) supported by O, Na and proton conducting solid electrolytes.
