The use of ion conducting membranes in combination with plasma's for nitrogen fixation processes [1,2] poses new research questions on the influence of surface charge and electric fields on the plasma-electrocatalytic processes taking place on the membrane surface. Possible processes such as the exchange of electrons between electrodes/electrocatalysts and reactants can alter reaction pathways and decrease activation barriers, opening routes to modify the rate of electrochemical reactions.<br/>In this contribution I will present an overview of the possible plasma-electrocatalytic mechanisms which can occur during the plasma-membrane interaction. This overview is mainly aimed to provide an inspiration for further experimental and modeling studies of this novel combination of plasma's and ion conducting membranes. These insights might provide novel pathways to higher conversion rates and higher selectivity of the desired chemical products.
